Question

Andrew has $65.50. He is paid $11.50 for each earbud case he sells. He has a goal of earning $146. Write an equation to determine the number of earbud cases he must sell to meet his goal, then solve.​

Answer 1

11.50x + 65.50 = 146

He must sell 7 earbud cases to meet his goal.

Explanation:

11.50x + 65.50 = 146

11.50x = 146 - 65.50

x = 80.50/11.50

x = 7
