Question

The drama club is planning a fundraiser to buy costumes and props for an upcoming play. They spend $500 to buy candy bars. They will earn $0.50 in profit for each bar they sell.

Write an equation in slope-intercept form to determine their profit (p) based on the number of candy bars sold (c) .

Answer 1

p = 0.50c -500

Explanation:

You want an equation for the profit (p) in terms of candy bars sold (c), given that $0.50 in profit is earned on each one, and the club spent $500 to buy them.

Profit

revenue = 0.50c

The club's cost is the $500 they spent on the purchase of those candy bars.

Then the profit (p) is the difference ...

p = 0.50c -500
