Pamela has $10 more than Eva. Emily has thrice as much money as Pamela. They have a total of $175.
- How much money does Pamela have?
- How much money does Emily have?
(a)
Amount that Pamela has = 1 u
Amount that Eva has = 1 u - 10
Amount that Emily has = 3 u
Total amount that they has
= 1 u + 1 u - 10 + 3 u
= 5 u - 10
5 u - 10 = 175
5 u = 175 + 10
5 u = 185
1 u = 185 ÷ 5 = 37
(b)
Amount that Emily has
= 3 u
= 3 x 37
= $111
Answer(s): (a) $37; (b) $111
