Question

Last week Aiden earned $50 for working 8 hours. At this rate, how

many hours would he have to work to earn $175?

Answer 1

x = 28

Explanation:

We can write a proportion to solve

50 dollars 175 dollars

--------------- = --------------------

8 hours x hours

Using cross products

50x = 8 * 175

Divide each side by 50

x = 8 * 175 / 50

x = 28

Answer 2

`\huge\boxed{\sf 28 \ hours}`

Explanation:

Given that,

$50 = 8 hours

Using unitary method.

Divide both sides by 50

$1 = 8/50 hours

$1 = 0.16 hours

Multiply 175 to both sides

$175 = 0.16*175 hours

$175 = 28 hours

`\rule[225]{225}{2}`
