Ormond’s dad Luther sells solar panels. He receives a salary of $400 a week plus 1.2% commission on his sales. If his income last week was $1360, how much were his sales for the week?
Let x represent Luther’s sales for the week. Then:
$400 + 0.012x | = | $1360 |
0.012x | = | $960 |
x | = | $960/0.012 |
x | = | $80,000 |
