Answer 3

Suppose Amount of hours Cindy worked in the first job is x and the second job is y.

(At the first job, Cindy earns $6.50 per hour. At the second job, she earns $10.25 per hour)

Rate of x = $6.50 per hour
Rate of y = $10.25 per hour

(Cindy works twice as many hours at the first job as she does at the second)

x = 2y

(Cindy earned $372 last week)

Rate of x * x + Rate of y * y = Total Price

6.5x + 10.25y = 372

i think B is correct one.

Answer 4

X= how much she earns in the first y how much she earns the second
so x+2y=372
