Question

A plumber's assistant's rate of pay is $0.75 per cubic foot of earth moved. He moves 220 cubic feet of earth to dig a trench. He moves the same amount to fill the trench. What is his pay for this job?

Answer 1

0.75 per cubic foot of earth move.

Ignore all the words, you multiply 220 by 0.75 twice in order to find out what he is paid.

220 * 0.75 = $165

You are multiplying by 220 again because he moves the same amount to fill the trench.

220 * 0.75 = $165

$165 + $165
=
Your Answer:
$330

Answer 2

220 * 0.75 = $165
$165 + $165 =
$330
