The amount he put into the first account at 2% interest will be $8,000 and into the second account at 7% interest will be $42,000.
Given that,
Amount invested by Alex = $50,000,
Total interest earned = 6.2%,
Now,
Let,
Amount invested at 2% = x,
So,
Amount invested at 7% = (50,000 - x),
So,
According to the question,
7%(50000 - x) + 2%(x) = 6.2% * 50,000
we get,
0.07(50000 - x) + 0.02(x) = 0.062 * 50,000
3500 - 0.07x + 0.02x = 3100
3500 - 0.05x = 3100
We get,
0.05x = 3500 - 3100
0.05x = 400
x = 8000,
So,
Amount invested at 2% = $8000,
So,
Amount invested at 7% = (50,000 - 8000) = $42,000,
Hence we can say that the amount he put into the first account at 2% interest will be $8,000 and into the second account at 7% interest will be $42,000.

A person at the mall purchased 4 shirts at an average price of $14. How much did the 5th shirt cost if the average after the 5th shirt was purchased changed to $16 per shirt?
GIVING BRAINLIEST AND THANKS
Answer: $24
Step-by-step explanation:
14+14+14+14=56
56+24=80
80/5
16
The 5th shirt cost $24 if the average after the 5th shirt was purchased changed to $16 per shirt.
Let's consider the total cost of the first 4 shirts:
Total cost of first 4 shirts = 4 shirts * $14/shirt = $56
Now, let's assume the cost of the 5th shirt is "x" dollars. After purchasing the 5th shirt, the total cost of all 5 shirts would be:
Total cost of all 5 shirts = $56 + x
Given that the average price after the 5th shirt was purchased is $16, we can set up an equation using the average formula:
Average price = Total cost / Number of shirts
$16 = ($56 + x) / 5
Solving for x:
$16 * 5 = $56 + x
$80 = $56 + x
x = $80 - $56
x = $24
So, the cost of the 5th shirt (x) is $24. This means that the person purchased the 5th shirt for $24 in order to bring the average price of all 5 shirts to $16 per shirt.

You are comparing two savings accounts based on the interest you would earn and the fees they charge. Assuming you have a savings account with an average balance of $500, which combination of interest rates and fees are a better deal? (Hint: Using a one year period, determine the balance that you would have at Bank A and Bank B).
Using simple interest, the better deal is given by Bank B.
What is the missing information?The options are missing, but they are given as follows:
Bank A: An account with 10% annual interest rate and $5/month in fees.Bank B: An account with 2% annual interest rate and no fees.Simple InterestSimple interest is used when there is a single compounding per time period.
The amount of money after t years in is modeled by:
A(t) = A(0)(1 + rt)
In which:
A(0) is the initial amount.r is the interest rate, as a decimal.For Bank A, the balance, without the fee, will be given by:
A(1) = 500(1 + 0.1) = $550.
Removing the fee:
550 - 12 x 5 = $490.
For Bank B, the balance is given by:
A(1) = 500(1 + 0.02) = $510.
No fee, 510 > 490, hence Bank B offers the better deal.

Collect the like terms
So, we have
22x - 6x = 4 + 79 - 3
Evaluate the like terms
So, we have
16x = 80
Divide both sides by 16

Determine the most convenient method to graph the following line.
3x+2y=12
The most convenient method to graph the line is to plot the equation y = -3/2x + 6 to represent the equation 3x + 2y = 12
What are linear equations?Linear equations are equations that have constant average rates of change.
Note that the constant average rates of change can also be regarded as the slope or the gradient
How to determine the method of plotting the graph?The equation is given as
3x + 2y = 12
The above equation is a linear equation
All forms of equation can be conveniently plotted by a graphing utility
However, the best way is to start by simplifying the equation
So, we have
3x + 2y = 12
Divide through the equation by 2
So, we have
3/2x + y = 6
Make y the subject of the equation
So, we have
y = -3/2x + 6
This means that we plot the equation y = -3/2x + 6 to represent the equation 3x + 2y = 12

A salesperson’s commission rate is 6%. What is the commission from the sale of $33,000 worth of furnaces? Use pencils and paper. Suppose sales would double. What would be true about the commission? Explain without using any calculations.
The commission for the sale of $33000 worth of items at 6 percent is $1980 and if the sale doubles than the commission would be $3960
How to solve for the commissionGiven that the commission rate is 6%
If the sales done is 33000 dollars then the commission received by the agent would be:
33000 * 0.06 = 1980
Now if the sale doubles we would have 33000 x 2
= 66000 dollars
then the commission received would be
66000 x 0.06
= $3960
Hence we would say that the commission for the sale of $33000 worth of items at 6 percent is $1980 and if the sale doubles than the commission would be $3960
