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!
I think you start with 10 +.15s = 380

100, not 10

100 + 0.15s = 380
0.15s = 280
s = 1866.6666 = 1867
