Gabrielle and Rob each earn $22 an hour, and each works 40 hours this week. Rob spends 1/2 of his earnings this week on bills an
Zielflug [23.3K]

The amount spent is an illustration of subtraction and proportions

The amount left in his earnings is $414.25

<h3>How to determine the amount left in his earnings?</h3>

The given parameters are:

Rate = $22 per hour

Time = 40 hours

So, the total earnings is:

Total = $22 * 40

Evaluate

Total = $880

He spent half on bills.

So, we have:

Bills = 0.5 * $880

Bills = $440

He buys a video game for $25.75

So, the amount left is

Amount left = $880 - $440 - $25.75

Amount left = $414.25

Hence, the amount left in his earnings is $414.25
