Answer:
$142.60
Step-by-step explanation:
an increase of 15% on the original cost of 100% means
percentage increase = 100% + 15% = 115% , then
cost = 115% × $124 = [tex]\frac{115}{100}[/tex] × $124 = 1.15 × $124 = $142.60
#1 You are in charge of ordering hats for a youth
baseball team. Each hat costs $22.50. There are at
least 10 but no more than 16 players on the
baseball team. The total cost of ordering hats can
be modeled by the function f(x)=22.50x,
where x represents the number of hats ordered. answer
The range of the function f(x) = 2.250x is 22.5 <= f(x) <= 36
What is the range of a function?The range of a function is the set of output values of the graph.
This in other words mean the range of a function is the set of y values of the graph.
How to determine the range of the function?The function is given as
f(x) = 2.250x
Where there are at least 10 but no more than 16 players on the baseball team
This means that the domain of the function is
10 <= x <= 16
Substitute the domain values in the given function
So, we have
f(x) = 2.250x
f(10) = 2.250 * 10
Evaluate
f(10) = 22.5
f(x) = 2.250x
f(16) = 2.250 * 16
Evaluate
f(16) = 36
The range of the function is then represented as
f(10) <= f(x) <= f(16)
So, we have
22.5 <= f(x) <= 36
Hence, the range of the function f(x) = 2.250x is 22.5 <= f(x) <= 36

Death valley is a desert in northern california with many place of interest. one such place is the badwater basin, the elevation is
-282 feet. at another location, salt creek trail, the elevation is-220 feet. write an inequality to compare the elevations and state
which elevation is closer to sea level.
The inequality comparing the elevations is -220 > -282 and -220 feet is closer to sea level.
The elevation of Bad Water Basin = -282 feet
The elevation of the Salt Creek = -220 feet
We are asked to compare the elevations and find which is greater than the other.
So we know that on a number line -220 is greater than -282.
This can be understood in the same sense that -1 > -2 on the number line.
So the inequality comparing the elevations is -220 > -282.
Now consider the sea level as 0 on the number line.
Then clearly -220 is closer to 0 on number line.
Hence the elevation closer to the sea level = -220 feet.

The solved logarithmic function is log (2x + y) = 4 log (2) and log (4x - y) = 0 for 2x + y = 2⁴ and 4x - y = 1 respectively.
What is a logarithmic and exponential function?
Logarithmic functions and exponential functions are inverses of each other. The logarithmic function is denoted by using the word log while exponential by using the alphabet, e. For example log 10 = 1 and e^2.
Solving the given expressions: 2x + y = 16 and 4x - y = 1
Applying given properties of logarithmic and exponential function;
log a + log b = log (ab)
4 log x = log x⁴
e^(log x) = 1
e^(x + y) = (e^x) × (e^y)
Take the expression, 2x + y = 16
Applying log on both sides, we get,
log (2x + y) = log (16)
log (2x + y) = log (2⁴)
log (2x + y) = 4 log (2)
To Check Results,
Taking exponential on both sides,
e^[log (2x + y)] = e^(4 log 2)
2x + y = e^(log 2⁴)
2x + y = 2⁴
2x + y = 16
Thus, the answer is verified.
Take expression, 4x - y = 1
Applying log on both sides, we get,
log (4x - y) = log 1
log (4x - y) = 0
To Check Results,
Taking exponential on both sides,
e^[log (4x - y)] = e^0
4x - y = 1
Thus, the answer is verified.
Hence, the solved expression is log (2x + y) = 4 log (2) and log (4x - y) = 0 for 2x + y = 2⁴ and 4x - y = 1 respectively.

The greatest common factor of 9 and 48 is 3.
What is the greatest common factor?The greatest common factor (GCF) is the largest positive integer that divides two or more numbers without leaving a remainder. In other words, it is the largest number that is a factor of both (or all) of the given numbers.
For example, the GCF of 12 and 18 is 6, beca
To find the greatest common factor (GCF) of 9 and 48, we need to determine the largest number that both 9 and 48 can be divided by evenly.
We can start by listing the factors of each number:
9: 1, 3, 9
48: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48
Then we can look for the greatest factor that appears in both lists. In this case, the greatest common factor of 9 and 48 is 3, since it is the largest number that appears in both lists of factors.
Therefore, the GCF of 9 and 48 is 3.

Find the average rate of change of g(2) = -4 + 4 between the points (-3,16) and (4,-12)
The average rate of change of the function between the points is -4/7
What are average rates of change?The constant average rates of change of a function is also regarded as the slope or the gradient of the function
How to determine the average rates of change?Here, we have the points to be
(-3, 16) and (4, 12)
The average rates of change between these points is calculated as
Average rate of change = [f(b) - f(a)]/[b - a]
So, we have
Average rate of change = [12 - 16]/[4 + 3]
Evaluate the sum and the difference
So, we have
Average rate of change = -4/7

The cost of one packet of biscuit is £1.60.
What is the cost of one packet of biscuit?The total amount that Aisha paid for the items she purchased is a function of the total cost of bread rolls, ketchup and biscuits.
Total cost of the items purchased = total cost of bread rolls + total cost of biscuits + total cost of ketchup
Total cost of bread rolls = cost per packet x number of packets bought
2 x £1.20 = £2.40
Total cost of ketchup = cost of one bottle x number of bottles bought
1 x £2.10 = £2.10
Total cost of biscuits = cost of one packet x number of packets bought
3 x b = 3b
Total cost = £2.40 + £2.10 + 3b = £4.50 + 3b
Total amount paid by Aisha = note given - change received
£10 - 70p
£10 - £0.70 = £9.30
Total amount paid by Aisha = total cost
£9.30 = £4.50 + 3b
£9.30 - £4.50 = 3b
£4.80 = 3b

Running Back Score: 11.75
Wide Receiver: 1.05 less than Running Back (11.75 - 1.05), which would be 10.7 points.
