The total amount that Esther, Jane and Kathy have is repeated. Make the total amount that Esther, Jane and Kathy have the same. LCM of 6 and 8 is 24.
Amount that Esther had less than Gabby
= 9 u - 4 u
= 5 u
5 u = 90
1 u = 90 ÷ 5 = 18
Total sum of money that 4 girls received
= 9 u + 4 u + 5 u + 15 u
= 33 u
= 33 x 18
= $594
Answer(s): $594
