As a salesperson you will earn $600 per month plus a commission of 20% of sales. Find the minimum amount of sales you need to make in order to receive a total income of at least $1500 per month.
Let the amount of sales be s. The phrase at least means greater than or equal to. Since 20% is 0.2, We want to know when:
0.20s + 600 >= 1500
We type this inequality into our search engine to solve for s and we get:
s >= 4500
