Question

Suppose a model airplane club published a newsletter. Expenses are $0.90 for printing plus $600 for research and writing. They charge $1.50 per copy of the newsletter. How many copies must the club sell to break even? Write let statements and equations to solve. Show all your work.

A. The club must sell ___ copies to break even.
B. 600 + 0.90x = 1.50x
C. 0.90x = 600
D. 1.50x = 600

Answer 1

To find the number of copies the club must sell to break even, set up an equation and solve for x.

Step-by-step explanation:

To find the number of copies the club must sell to break even, we can set up an equation.

Let x be the number of copies sold.

The total expenses for the club can be calculated as follows:

Expenses = printing expense + research and writing expense = $0.90 + $600 = $600.90

The total revenue for the club can be calculated as follows:

Revenue = cost per copy * number of copies = $1.50x

Since the club wants to break even, the total expenses should be equal to the total revenue:

$600.90 = $1.50x

Solving for x, we get:

x = $600.90 / $1.50 = 400.60

Rounding to the nearest whole number, the club must sell 401 copies to break even.
