Peter works 38 hours per week and earns $7.25 per hour. His employer gives him a raise that increases his weekly gross play to $307.80. What is the increase in Peters weekly gross pay?

You multiply 38*$7.25 equals $275.5

Subtract new weekly gross pay raise with regular gross pay

$307.80-$275.5 = $32.3 cents in raise

Increase in Peter's weekly gross salary is $32.30

Step-by-step explanation:

Peter works 38 hours per week and earns $7.25 per hour.

Then weekly gross pay = 38*7.25 = $275.50

His employer gives him a rise so that his gross pay increases to $307.80

Now we can calculate the weekly gross increase in the pay by subtracting the pay after increase from the pay before the increase = 307.80 - 275.50

= $32.30

Therefore, increase in Peter's weekly gross salary is $32.30
