Tiffany has $8 more than Lucy. Tammy has thrice as much money as Tiffany. They have a total of $112.
- How much money does Tiffany have?
- How much money does Tammy have?
(a)
Amount that Tiffany has = 1 u
Amount that Lucy has = 1 u - 8
Amount that Tammy has = 3 u
Total amount that they has
= 1 u + 1 u - 8 + 3 u
= 5 u - 8
5 u - 8 = 112
5 u = 112 + 8
5 u = 120
1 u = 120 ÷ 5 = 24
(b)
Amount that Tammy has
= 3 u
= 3 x 24
= $72
Answer(s): (a) $24; (b) $72
