Nadia has a summer job in an electronics store. She is paid $400 per week, plus 5% commission on the total value of her sales.
Nadia's average earnings are $780 per week. What is the average value of her weekly sales?
------
E(x) = 400 + 0.05x
------
Solve::
400 + 0.05x = 780
0.05x = 380
x = 38000/5
x = 7600 dollars (amt. of sales)
