Opal has $4 more than Xylia. Lucy has four times as much money as Opal. They have a total of $188.
- How much money does Opal have?
- How much money does Lucy have?
(a)
Amount that Opal has = 1 u
Amount that Xylia has = 1 u - 4
Amount that Lucy has = 4 u
Total amount that they has
= 1 u + 1 u - 4 + 4 u
= 6 u - 4
6 u - 4 = 188
6 u = 188 + 4
6 u = 192
1 u = 192 ÷ 6 = 32
(b)
Amount that Lucy has
= 4 u
= 4 x 32
= $128
Answer(s): (a) $32; (b) $128
