ulie made $90 more than Ally. If their total earnings for the week are $995, how much didi each girl make?
1 answer:
Answer:
Pat earnings = $181
Ally earnings = $362
Julie earnings = $452
Step-by-step explanation:
Let
Pat earnings = x
Ally earnings = 2x
Julie earnings = 2x + 90
Total earnings = $995
Total earnings = Pat earnings + Ally earnings + Julie earnings
995 = x + 2x + (2x + 90)
995 = 3x + 2x + 90
995 = 5x + 90
995 - 90 = 5x
905 = 5x
x = 905/5
x = 181
Pat earnings = x = $181
Ally earnings = 2x
= 2(181)
= $362
Julie earnings = 2x + 90
= 2(181) + 90
= 362 + 90
= $452
