Linda has $9 more than Jade. Barbara has twice as much money as Linda. They have a total of $191.
- How much money does Linda have?
- How much money does Barbara have?
(a)
Amount that Linda has = 1 u
Amount that Jade has = 1 u - 9
Amount that Barbara has = 2 u
Total amount that they has
= 1 u + 1 u - 9 + 2 u
= 4 u - 9
4 u - 9 = 191
4 u = 191 + 9
4 u = 200
1 u = 200 ÷ 4 = 50
(b)
Amount that Barbara has
= 2 u
= 2 x 50
= $100
Answer(s): (a) $50; (b) $100
