The total amount that Wendy and Min have is repeated. Make the total amount that Wendy and Min have the same. LCM of 4 and 5 is 20.
The total amount that Abi, Wendy and Min have is repeated. Make the total amount that Abi, Wendy and Min have the same. LCM of 6 and 8 is 24.
Amount that Barbara had more than Wendy
= 9 u - 5 u
= 4 u
4 u = 64
1 u = 64 ÷ 4 = 16
Total sum of money that 4 girls received
= 9 u + 4 u + 5 u + 15 u
= 33 u
= 33 x 16
= $528
Answer(s): $528
