Answer 1

85 hours

Explanation:

Given : Rachel earned $34 in 4 hours

To Find : how much she will earn in 4 hours?

Solution:

Since we are given that

She earns in 4 hours = $34

So, She earns in 1 hour =
`(34)/(4) = 8.5`

She earns in 10 hours:

`= 8.5*10`

`= 85`

Thus she earns $85 in 10 hours .

Hence Rachel earns $85 if she works 10 hours at same hourly rate.

Answer 2

Rachel will earn $85 in 10 hours.

Explanation:

Rachel earned $34 in 4 hours at her job today.

Suppose, she will earn
`x` dollar in 10 hours tomorrow.

So, according to ratio of 'dollar' and 'hours', the equation will be.....

`(34)/(4)=(x)/(10)`

After cross multiplying, we will get.....

`4x= 34*10\\ \\ 4x= 340\\ \\ x=(340)/(4)=85`

Thus, Rachel will earn $85 in 10 hours.
