Betty has $6 more than Mary. Usha has twice as much money as Betty. They have a total of $166.
- How much money does Betty have?
- How much money does Usha have?
(a)
Amount that Betty has = 1 u
Amount that Mary has = 1 u - 6
Amount that Usha has = 2 u
Total amount that they has
= 1 u + 1 u - 6 + 2 u
= 4 u - 6
4 u - 6 = 166
4 u = 166 + 6
4 u = 172
1 u = 172 ÷ 4 = 43
(b)
Amount that Usha has
= 2 u
= 2 x 43
= $86
Answer(s): (a) $43; (b) $86
