As a salesperson, Brittany earns $1,200 a month plus 7.5% commission on her sales. She needs to earn at least $3,300 a month to pay all her bills. The following inequality can be used to find the amount of sales Brittany needs to have each month.
1200 plus 0.075 x greater than or equal to 3300
What is the solution to the inequality?
work out
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.
