Answer:
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.
