(a)
The total amount that Asher, Sean and Irene had is repeated. Make the total amount the same. LCM of 3 and 15 is 15.
Asher's shareTotal amount =
515 =
13 (b)
Amount that Irene had less than Asher
= 5 u - 3 u
= 2 u
2 u = 22
1 u = 22 ÷ 2 = 11
Total amount that Asher, Sean and Irene had
= 15 u
= 15 x 11
= $165
Answer(s): (a)
13; (b) $165
