The total amount that Joelle and Dana have is repeated. Make the total amount that Joelle and Dana have the same. LCM of 5 and 3 is 15.
The total amount that Gwen, Joelle and Dana have is repeated. Make the total amount that Gwen, Joelle and Dana have the same. LCM of 4 and 5 is 20.
Amount that Gwen had less than Emma
= 8 u - 5 u
= 3 u
3 u = 30
1 u = 30 ÷ 3 = 10
Total sum of money that 4 girls received
= 8 u + 5 u + 3 u + 12 u
= 28 u
= 28 x 10
= $280
Answer(s): $280
