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?

220 * 2 * $.75 = ?

330.00 To calculate the plumber's assistant's pay for this job, we need to determine the total amount of earth moved and then multiply it by the pay rate.

First, let's calculate the total amount of earth moved by adding the amount moved to dig the trench (220 cubic feet) with the amount moved to fill the trench (also 220 cubic feet).

220 cubic feet + 220 cubic feet = 440 cubic feet

Next, we multiply the total amount of earth moved (440 cubic feet) by the pay rate ($0.75 per cubic foot) to find the pay for this job.

440 cubic feet * $0.75/cubic foot = $330

Therefore, the plumber's assistant's pay for this job would be $330.
