Question

A salesperson earns $500 per month plus a commission of 20% of sales. Describe the sales needed to receive a total income that exceeds $3200 a month

Answer 1

500 + 0.2x = 3200
0.2x = 2700
x = 2700 / 0.2
x = 13500

We can check by plugging in 13500

So we have
500 + 0.2(13500) = 3200
500 + 2700 = 3200
3200 = 3200

So the answer is any amount of over 13500 will result in more than $3200 earned.
