Gabby has $11 more than Jean. Gillian has five times as much money as Gabby. They have a total of $101.
- How much money does Gabby have?
- How much money does Gillian have?
(a)
Amount that Gabby has = 1 u
Amount that Jean has = 1 u - 11
Amount that Gillian has = 5 u
Total amount that they has
= 1 u + 1 u - 11 + 5 u
= 7 u - 11
7 u - 11 = 101
7 u = 101 + 11
7 u = 112
1 u = 112 ÷ 7 = 16
(b)
Amount that Gillian has
= 5 u
= 5 x 16
= $80
Answer(s): (a) $16; (b) $80
