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
Turn it to improper fractions.
4 1/4 divided by 2/7
Divide them.
17/4 divided by 2/7
17 2 17 x 7
--- ÷ --- = --------- = 119/8 OR 14 7/8
4 7 4 x 2

Distribute to take out the parentheses.
(x + 8) - (-3x - 5)
Combine like terms.
x + 8 + 3x + 5
Answer.
4x + 13
