Help me please ! I can’t fail this :( .

Part A: B. 34/4 = e/10

Part B: Rachel can earn $85 in 10 hours.

Step-by-step explanation:

For Part A:

We know Rachel can earn $34 in 4 hours. We need to set up an equation so we know how much she can earn in 10 hours. 34/4 is on the left side of the equation, since we already know that. However, we don't know what e (earnings) is, so put that on the right over 10. Thus, the equation is 34/4 = e/10, which is B.

For Part B:

With the equation we just happened to figure out, cross multiply to find e.

34/4 = e/10

4e = 340

Divide both sides by 4

4e/4 = 340/4

e = 85

Rachel can earn $85 in 10 hours.

(Work Check:

34/4 = $8.50/hr

85/10 = $8.50/hr

These two values equal the same rate, so e as 85 is correct.)

the correct answer is 45x

9×5=45 then add the x
