(a)
The total amount that Tim, Glen and Lynn had is repeated. Make the total amount the same. LCM of 3 and 15 is 15.
Tim's shareTotal amount =
515 =
13 (b)
Amount that Lynn had less than Tim
= 5 u - 2 u
= 3 u
3 u = 36
1 u = 36 ÷ 3 = 12
Total amount that Tim, Glen and Lynn had
= 15 u
= 15 x 12
= $180
Answer(s): (a)
13; (b) $180
