A store owner buys cell phones for $40 and marks up the price by 25%. What is the sale price of a phone?
Answer:
$50
Step-by-step explanation:
Price of the cell phone bought p = $40
% of markup in price = 25%
Selling price of the cell phone = p + (%)p
Selling price of the cell phone = P + (0.25)p
Selling price of the cell phone = p + 0.25p
Selling price of the cell phone = 1.25p
Selling price of the cell phone = 1.25 * $40
Selling price of the cell phone = $50
A land developer wants to divide up 9/10 of an acre Of land into equally sized lots for houses. He wants to build nine houses. How big can he make each lot? Write your answer as a fraction or as a whole or a mixed number
Answer:
1/10 acres
Step-by-step explanation:
A land developer wants to divide up 9/10 of an acre Of land into equally sized lots for houses. He wants to build nine houses. How big can he make each lot?
This is calculated as:
1 lot = 1 house
Hence:
9 house = 9/10 acres
1 house = x
Cross Multiply
9x = 9/10 acres
x = 9/10 ÷ 9
x = 9/10 × 1/9
x = 1/10 acres
Hence, the size of each lot when divided equally = 1/10 acres

A boat is pulled in by means of a winch located on a dock 10 feet above the deck of the boat. Let the angle of elevation ø = 18 degrees. Find the length s of the rope.
9514 1404 393
Answer:
32.4 feet
Step-by-step explanation:
The applicable relationship between angle and triangle lengths is ...
Sin = Opposite/Hypotenuse
The dock height is the side of the triangle opposite the given angle. The desired length is the hypotenuse of the triangle, so we have ...
sin(18°) = (10 ft)/s
s = (10 ft)/sin(18°) = (10/0.30902) ft
s ≈ 32.4 ft
The length of the rope is about 32.4 feet.

Is there a proportional relationship between the number of pounds of apples and their cost? Is there a proportional relationship between the number of toppings on a pizza and its cost? Explain how you know.
The question is incomplete, the complete question is;
Based on the information in the table, is the cost of the apples proportional to the weight of apples?
Pound of apples:
2

$7.52
$9.40
2. Based on the information in the table, is the cost of the pizza proportional to the number of toppings?
Number of toppings:
2

4
5
Cost of pizza:
$11.99
$13.49
$14.99
$16.49
Answer:
See explanation
Step-by-step explanation:
Based on the information provided, there is a proportional relationship between the cost of the apples and the weight of the apples as well as between the number of toppings and the cost of the pizza.
We know that there is a proportional relationship when there is a linear increase or decrease in the two quantities in the relationship. This increase or decrease is usually by a constant value.
In the relationship between the weight of apples and the cost of apples, the cost of apples increases steadily by $1.88 which shows a proportional relationship.
Also, in the relationship between the number of toppings and the cost of pizza, the cost of pizza increases by $1.5 which shows a proportional relationship between the two.

A transaction is positive if there is a sale and negative when there is a return. Each time a customer uses credit card for a transaction, the credit company charges Isabel. The credit company charges 1.5% of each sale and a fee of 0.5 % for returns
Full question:
A transaction is positive if there is a sale and negative when there is a return. Each time a customer uses credit card for a transaction, the credit company charges Isabel. The credit company charges 1.5% of each sale and a fee of 0.5 % for returns
Let x represent the amount of a transaction and let f(x) represent the amount Isabel is charged for the transaction. Write a function that expresses f(x)
Answer:
f(x)= 0.015(x)
f(x)= 0.005(x)
Explanation:
If Isabel makes a sale, she has a positive transaction and therefore is charged 1.5%(which is 0.015) by the credit company for the transaction. If the product is returned, it is a negative transaction and the credit company charges 0.5%(which is 0.005) for the transaction. The functions for positive and negative transactions would be different as indicated in the answer since transactions( given by x) are different- positive and negative.

The price of a can of green beans is raised from $0.50 to $0.60. What is the percent increase in the price of the can of green beans?
Answer:
20%
Step-by-step explanation:
Here, we want to calculate the percentage increase in the price of a can of green beans
Mathematically, we use the formula below;
(new price - old price)/old price * 100%
From the question;
old price = $0.50
new price = $0.60
So we have;
(0.6-0.5)/0.5 * 100%
= 0.1/0.5 * 100%
= 20%
