Answer:
Chris has $ 72, Michael has $ 24, and Nicole has $ 17.
Step-by-step explanation:
Given that Nicole, Chris and Michael have a total of $ 113 in their wallets, and Nicole has $ 7 less than Michael, while Chris has 3 times what Michael has, to determine how much each one has, the following calculation must be performed:
Nicole: M - 7
Michael: M
Chris: 3M
3M + M + M -7 = 113
5M - 7 = 113
5M = 113 + 7
5M = 120
M = 120/5
M = 24
Michael: 24
Nicole: 24 - 7 = 17
Chris: 24 x 3 = 72
So Chris has $ 72, Michael has $ 24, and Nicole has $ 17.
