Question

1) A local fast food restaurant takes in $9000 in a 4 hour

period. Estimate how many hours it would take the same
restaurant to earn $20,250.

Answer 1

Answer: 9 hours

Explanation:

Assuming they keep earning money at the same rate, we will set up a proportion to help us solve.

`\displaystyle \frac{\$9,000}{4\;\text{hours}} =\frac{\$20,250}{x\;\text{hours}}`

Next, we will cross-multiply.

$9,000 * x = $20,250 * 4

$9,000x = $81,000

x = 9 hours

It will take the same restaurant about 9 hours to earn $20,250.
