Shannon has $4 more than Gem. Tina has thrice as much money as Shannon. They have a total of $151.
- How much money does Shannon have?
- How much money does Tina have?
(a)
Amount that Shannon has = 1 u
Amount that Gem has = 1 u - 4
Amount that Tina has = 3 u
Total amount that they has
= 1 u + 1 u - 4 + 3 u
= 5 u - 4
5 u - 4 = 151
5 u = 151 + 4
5 u = 155
1 u = 155 ÷ 5 = 31
(b)
Amount that Tina has
= 3 u
= 3 x 31
= $93
Answer(s): (a) $31; (b) $93
