The total amount that Dana and Jean have is repeated. Make the total amount that Dana and Jean have the same. LCM of 4 and 5 is 20.
The total amount that Kathy, Dana and Jean have is repeated. Make the total amount that Kathy, Dana and Jean have the same. LCM of 6 and 8 is 24.
Amount that Kathy had less than Esther
= 9 u - 4 u
= 5 u
5 u = 70
1 u = 70 ÷ 5 = 14
Total sum of money that 4 girls received
= 9 u + 4 u + 5 u + 15 u
= 33 u
= 33 x 14
= $462
Answer(s): $462
