Question

The Math Club is sponsoring a bake sale. If their goal is to raise at least $300, how many pies must they sell at $6.00 each in order to meet that goal? Write, solve, and graph an inequality that represents this situation.

Answer 1

inequality: 6x ≤ 300 solution: x ≤ 50 (at least 50 pies must be sold)

x = number of pies
6x ≤ 300
/6 /6
x ≤ 50

Answer 2

Given:
bake sale at least $300
price of each pie is $6.00
let the number of pies be represented by x.

Write the inequality:
6x > 300

Solve the inequality:
6x > 300
÷6 ÷6
x > 50

Graph the inequality.
y = 6x

x is the number of pies sold; x at least 50 and gradually increases.
y is the total sales
