Joseph works at a car dealership and earns a flat $450.00 per week. He also earns 3% of his sales each week. Joseph needs to earn at least $1,100.00 per week to make his monthly budget. How much does he need to sell each week in order to make his budget goal?

Joe needs to sell $21,667 in goods to end up with a weekly income of $1,100.

Step-by-step explanation:

Let's write an equation that describes this situation, and then solve the equation for the necessary weekly sales.

Flat $450, plus 3% of his sales, add up to $1,100.

Let s represent the amount of sales.

Then $450 + 0.03s = $1,100, where 0.03 is the decimal equivalent of 3%.

Solving for s,

0.03s = $1,100 - $450 = $650.

Dividing both sides by 0.03, to isolate s, we get:

s = $650/0.03 = $21,667

Joe needs to sell $21,667 in goods to end up with a weekly income of $1,100.
