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.

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

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

x = number of pies

6x ≤ 300

/6 / 6

x ≤ 50
