Answer:

Since multiplication is reversible (to be division), we can switch the equation up.

75 ÷ 30 = x

So the answer is

75 ÷ 30 = 2.5

Rachel earned \$34$34 in 44 hours at her job today. She wants to know how much she could earn (e)(e) tomorrow if she works 1010
kari74 [83]

Answer:

<em>Rachel will earn $85 in 10 hours.</em>

Step-by-step explanation:

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

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

So, <u>according to ratio of 'dollar' and 'hours'</u>, the equation will be.....

\frac{34}{4}=\frac{x}{10}

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

4x= 34*10\\ \\ 4x= 340\\ \\ x=\frac{340}{4}=85

Thus, Rachel will earn $85 in 10 hours.
