There are two ways to calculate his new pay. Choose whichever is easier for you.

OPTION 1:
multiply current pay by 20%, then add the result to the current pay

Step 1:

=$91 increase

Step 2:
add pay increase from step 1 to current pay rate

=$455 + $91
=$546 new weekly rate

OPTION 2:
multiply current pay by (1 + 20%)

=($455)(1 + 20%)
