(a)
The total amount that Tom, Wesley and Irene had is repeated. Make the total amount the same. LCM of 3 and 15 is 15.
Irene's shareTotal amount =
215 (b)
Amount that Irene had less than Wesley
= 8 u - 2 u
= 6 u
6 u = 48
1 u = 48 ÷ 6 = 8
Total amount that Tom, Wesley and Irene had
= 15 u
= 15 x 8
= $120
Answer(s): (a)
215; (b) $120
