Shannon has $9 more than Kathy. Gwen has twice as much money as Shannon. They have a total of $179.
- How much money does Shannon have?
- How much money does Gwen have?
(a)
Amount that Shannon has = 1 u
Amount that Kathy has = 1 u - 9
Amount that Gwen has = 2 u
Total amount that they has
= 1 u + 1 u - 9 + 2 u
= 4 u - 9
4 u - 9 = 179
4 u = 179 + 9
4 u = 188
1 u = 188 ÷ 4 = 47
(b)
Amount that Gwen has
= 2 u
= 2 x 47
= $94
Answer(s): (a) $47; (b) $94
