1 answer

To find the solution to the inequality, we need to solve for the amount of sales Brittany needs to have each month.

1200 + 0.075x ≥ 3300

First, we subtract 1200 from both sides of the inequality:

0.075x ≥ 2100

Next, we divide both sides by 0.075:

x ≥ 28000

Therefore, Brittany needs to have at least $28,000 in sales each month in order to earn enough to pay all her bills.
