Ответ:
Chris = $68, Pablo = $24, Debra = $17
Step-by-step explanation:
C + P + D = 109
C = 4D
P = D + 7
4D + D + D + 7 = $109
6D + 7 = $109
Subtract 7 from both sides...
6D = 102
Divide both sides by 6...
D = $17
and Debra has 17 dollars which means...
C = 4(17)
C = $68
Chris has $68
P = 17 + 7
P = $24
and Pablo has $24!
