Question

This is a practice lesson Jake makes and sells pies. He sells each pie for $5.75. The materials to make each pie costs Jake $4.00. The boxes Jakes put the pies in cost $0.75 each. Jake wants to know how many pies (p) he needs to sell to earn a profit of at least $50. Which inequality should Jake use? A) 50 ≤ 5.75p - 4.75p B) 50 ≥ 5.75p - 4.75p C)50 ≤ 5.75p - 3.25 D)P ≤ 5.75(50) - 4.75p

Answer 1

Option A is correct.

Explanation:

Let p be the number of pies Jake sells. The profit Jake makes is the total price the pies are sold for ($5.75) minus the total cost of making them ($4.00 + $0.75 = $4.75). For the profit to be at least $50:

($5.75 - $4.75)p ≥ 50

Option A is another way of writing this answer (expand and flip).
