Olivia has $7 more than Esther. Tammy has four times as much money as Olivia. They have a total of $191.
- How much money does Olivia have?
- How much money does Tammy have?
(a)
Amount that Olivia has = 1 u
Amount that Esther has = 1 u - 7
Amount that Tammy has = 4 u
Total amount that they has
= 1 u + 1 u - 7 + 4 u
= 6 u - 7
6 u - 7 = 191
6 u = 191 + 7
6 u = 198
1 u = 198 ÷ 6 = 33
(b)
Amount that Tammy has
= 4 u
= 4 x 33
= $132
Answer(s): (a) $33; (b) $132
