HELP PLEASE!!!!
The question is: Carmella works 37.5 h per week for Century Home selling electronics equipment. She earns a base salary of $12/h and receives a commission of 5 cents for every dollar of sales she make.
Her chart goes like:
WSales($):Commission($): TotalSalary($)
0 0 blank
1000 50 blank
2000 blank blank
3000 blank blank
4000 blank blank
5000 blank blank
6000 blank blank
Then:Carmella's friends Maria and Sam work for two other electronics companies. The also work 37.5 h per week. Maria earns $8/h with a 10% commission and Sam earns $18/h with no commission.
a) One week, Carmella and Sam earned the same total salary. Determine each person's total sales and salary.
HOW DO I ANSWER THIS?! I TRIED TO DO THE ABOVE CHART FOR ALL THREE FRIENDS TO GET THE INFO TO GRAPH BUT THERE IS NO WEEKLY SALES I SEE WHEN SAM AND CARMELLA HAVE THE SAME TOTAL SALARY.
WHAT AM I DOING WRONG?!
I FILLED OUT THE CHARTS LIKE BUT FOR TOTAL SALARY, AM I SUPPOSED TO ADD THE PREVIOUS TOTAL SALARY TO THE NEXT ONE OR WHAT? PLEASE HELP ME WITH THIS QUESTION, PLEASE!

on x sales,
c = 12*37.5 + .05x
m = 8*37.5 + .10x
s = 18*37.5
during the week, sam made 675.00
so, we need
12*37.5 + .05x = 675.00
x = 4500
c = 450(salary) + 225(commission) = 675
