Engine Repair Work Example 19

WorkKey Level: 4
NATEF Task(s): Background

Problem:

Joe's Auto Repair shop ordered parts totaling $418.90. The supplier requires 25% down and 5% for shipping with each order. If Joe plans to send $125, will that amount be sufficient?


Solution:

A = (25%)(418.90) + (5%)(418.90)
A = (30%)(418.90)
A = (0.3)(418.90)
A = 125.67

No, $125 will not be sufficient. Joe needs to send $125.67.
