Question

George earns $455 per week. George recieves a 20% raise. How can george calculate his new weekly per rate?

Answer 1

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:
multiply pay by 20% increase
=$455 * 20%
=$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%)
=(455)(1.20)
=$546 new weekly rate


ANSWER: His new weekly rate is $546 per week.

Hope this helps! :)
