The manager of a home store is buying lawn chairs to sell at his store. Each pack of chairs contains 10 chairs. The manager will sell each chair at a markup of 20% of the wholesale cost, plus a $2.50 stocking fee.

a. Write an equation that represents the retail price of a chair, r, in terms of the wholesale price, w.

b. Use your equation to calculate the retail price of the chair if the wholesale price is $8.40.

c. Use your equation to calculate the wholesale price if the retail price is $13.30.

Answers

Answer:

Step-by-step explanation:

a. The required equation is r = 0.2w + 2.5 + w. b. The retail price of a chair is $12.58 if the wholesale price is $8.40. c. The wholesale price is $44 if the retail price is $13.30.

What is the Linear equation?

A linear equation is defined as an equation in which the highest power of the variable is always one.

a. The retail price of a chair is the wholesale price plus the markup and stocking fee. The markup is 20% of the wholesale price, so we can represent it as 0.2w. The stocking fee is a fixed amount of $2.50, so we can add it to the markup and wholesale price to get the retail price.

The equation that represents the retail price of a chair, r, in terms of the wholesale price, w is:

r = 0.2w + 2.5 + w

b. To calculate the retail price of a chair if the wholesale price is $8.40, we substitute 8.4 for w in the equation:

r = 0.2(8.4) + 2.5 + 8.4

r = 1.68 + 2.5 + 8.4

r = 12.58

So the retail price of a chair, if the wholesale price is $8.40, is $12.58.

c. To calculate the wholesale price if the retail price is $13.30, we can solve the equation for w.

r = 0.2w + 2.5 + w

13.3 = 0.2w + 2.5 + w

10.8 = 0.2w + w

8.8 = 0.2w

w = 8.8 / 0.2

w = 44

So the wholesale price, if the retail price is $13.30, is $44.

Answer: 25 cartons

========================================================

Explanation:

1 liter = 1000 mL

Note how 1000/200 = 5, which means that if one carton is 200 mL, then five cartons gets us 5*200 = 1000 mL = 1 liter. If it takes five cartons to get 1 liter, then we'll need five times as many cartons to get to 5 liters. So 5*5 = 25 cartons is our goal.

---------

We could also solve like this

(1 carton)/(200 mL) = (x cartons)/(5000 mL)

1/200 = x/5000

1*5000 = 200x .... cross multiply

5000 = 200x

200x = 5000

x = 5000/200 ..... divide both sides by 200

x = 25
