Answer:
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
I don't know how much money
Multiplying ,you get 18x^2+21x-24x-28. You simplify to get:
18x^2-3x-28.
