What percentage change is this from the $3500 per month?

Question

A woman making $3500 per month has her salary reduced by 20% because of sluggish sales. One year later after a dramatic improvement in sales she is given a 30% raise over her reduced salary. Find her salary after the raise.

Answer 1

1st year

 

Reduction of 20% is 100-20=80%

 

0.8*3500=$2,800

 

in first year due to reduction she makes $2,800

 

2nd year

 

increase of 30% is 100+30=130%

1.3*2800=$3,640

 

she currently earns $3,640
