Answer:
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.)
