Answer:
The value of money in the wallet of Charmaine ( x ) = $ 18
The value of money in the wallet of dale ( y ) = $ 26
The value of money in the wallet of Justin ( z ) = $ 72
Step-by-step explanation:
Let Money in the wallet of Charmaine = x
Money in the wallet of dale = y
Money in the wallet of Justin = z
Total money = $ 116
⇒ x + y + z = $ 116 ------- ( 1 )
Dale has $ 8 more than Charmaine.
⇒ y = 8 + x ----------------- ( 2 )
Justin has 4 times what Charmaine has.
⇒ z = 4 x -------------------- ( 3 )
Put the values of y and z in equation (1), we get
⇒ x + 8 + x + 4 x = 116
⇒ 6 x = 116 - 8 = 108
⇒ x =
⇒ x = $ 18
This is the value of money in the wallet of Charmaine.
Put the value of x in equation (2) we get,
⇒ y = 8 + 18
⇒ y = $ 26
This is the value of money in the wallet of dale.
Money in the wallet of Justin z = 4 x
⇒ z = 4 × 18
⇒ z = $ 72
This is the value of money in the wallet of Justin.
