Marilyn is a salesperson at Open to Clothes. Each month she earns $650 plus 6% of her total monthly sales. How much did she earn last month if her sales totaled $7200?

Her monthly income=$1,082

Step-by-step explanation:

Step 1: Express the total monthly pay:

The total monthly pay can be expressed as follows;

A=F + (R*T)

where;

A=the total monthly income

F=fixed income per month

R=commission rate

T=total monthly sales

In our case;

F=$650 a week

R=6%=6/100=0.06

T=$7200

replacing;

A=650 + (6% of 7,200)

A=650 + (0.06*7,200)

A=650+432=1,082

A=$1,082

Her monthly income=$1,082
