The student council is making corsages to sell at prom. They spent $350 on materials such as flowers, ribbons, elastic and pins. They are selling the corsages for $7.50 each. They need to
earn $700 to pay for prom decorations. Which inequality will determine the correct number of
corsages, c, that the class needs to sell to pay for the prom decorations?

The inequality 7.50c - 350 ≥ 700 can be used.

Step-by-step explanation:

Given that:

Amount spent on materials = $350

Amount the council needs to earn = $700

Selling price per corsage = $7.50

Number of corsages sold = c

Selling price per corsage * Number of corsages sold - amount spent on materials ≥ amount needs to be earned

Hence,

The inequality 7.50c - 350 ≥ 700 can be used.
