Diana has $8 more than Rachel. Winnie has four times as much money as Diana. They have a total of $178.
- How much money does Diana have?
- How much money does Winnie have?
(a)
Amount that Diana has = 1 u
Amount that Rachel has = 1 u - 8
Amount that Winnie has = 4 u
Total amount that they has
= 1 u + 1 u - 8 + 4 u
= 6 u - 8
6 u - 8 = 178
6 u = 178 + 8
6 u = 186
1 u = 186 ÷ 6 = 31
(b)
Amount that Winnie has
= 4 u
= 4 x 31
= $124
Answer(s): (a) $31; (b) $124
