Question

Don gets $25 for whitewashing a fence. How many fences would he have to whitewash to earn a trip to camp that costs $165.00?

Answer 1

You would need to divide 165 by 25

25 50 75 100 125 150 175

He would need to whitewash seven fences. Even though 25*7 = 175, its better to have more money then not enough and realistically you cant whitewash a fraction of a fence.

Answer 2

7 fences would he have to whitewash to earn a trip to camp that costs $165.00

Explanation:

Unit rate defined as the rates are expressed as a quantity as 1 such as 2 meter per seconds or 4 miles per hour.

As per the statement:

Don gets $25 for whitewashing a fence

⇒
`\text{Unit rate per fence} = \$ 25`

We have to find the fences would he have to whitewash to earn a trip to camp that costs $165.00.

`\text{Number of fences} = \frac{165}{\text{Unit rate per fence}}`

Substitute the given values we have;

`\text{Number of fences} = (165)/(25) = (33)/(5) = 6.6 \approx 7`

therefore, 7 fences would he have to whitewash to earn a trip to camp that costs $165.00
