Jonathon is starting a new job where he will earn $100 per week plus 15% commission on all sales. Write an equation and solve it to show what his sales were for a week if he earned $380.00? Round your answer to the nearest integer.

Thank you!

Solution

100 per week
15% commission

Let sales be x
So, amt earned by commission = 15% of x -----> 0.15x

So, we have :
100 + 0.15x = 380

0.15x = 380 - 100

0.15x = 280

x = 280 / 0.15

x = 1866.6666666666666667

So, approx sales is
1867
