(a)
The total amount that Brandon, Sam and Nora had is repeated. Make the total amount the same. LCM of 3 and 15 is 15.
Brandon's shareTotal amount =
515 =
13 (b)
Amount that Nora had less than Brandon
= 5 u - 3 u
= 2 u
2 u = 12
1 u = 12 ÷ 2 = 6
Total amount that Brandon, Sam and Nora had
= 15 u
= 15 x 6
= $90
Answer(s): (a)
13; (b) $90
