Answer:
C. $412.50
Step-by-step explanation:
We can use proportion:
12 meals --- 3 pounds
250 meals --- x pounds
x=(250 meals*3 pounds)/12 meals = 62.5 pounds
62.5 pound * $ 6.60/pound = $ 412.50
Jane has half as much as Elaine at first. The answer is 12, but I honestly just kept using random numbers. After spending 4, Jane has 8 and Elaine has 20.(12 times 2) - 4
So if Jade makes $306.25 a week and for every hour she works, she makes $8.75, then all you have to do is divide 306.25 by 8.75.
306.25/8.75 = 35 hours should be your answer
Let me know if that doesn't make sense or you still don't understand it :)
