Gabby has $6 more than Sarah. Sabrina has six times as much money as Gabby. They have a total of $146.
- How much money does Gabby have?
- How much money does Sabrina have?
(a)
Amount that Gabby has = 1 u
Amount that Sarah has = 1 u - 6
Amount that Sabrina has = 6 u
Total amount that they has
= 1 u + 1 u - 6 + 6 u
= 8 u - 6
8 u - 6 = 146
8 u = 146 + 6
8 u = 152
1 u = 152 ÷ 8 = 19
(b)
Amount that Sabrina has
= 6 u
= 6 x 19
= $114
Answer(s): (a) $19; (b) $114
