Carl, Albert and Riordan shared a sum of money. Carl and Albert received 90% of the total amount of money. Albert and Riordan received 25% of the total amount of money. Given that Albert received $24 less than Carl, how much was the sum of money that was shared by Albert and Riordan?

14 The total amount of money that Carl, Albert and Riordan shared is repeated. Make the total amount of money the same. LCM of 10 and 4 is 20.
Amount that Albert received less than Carl
= 15 u - 3 u
= 12 u
12 u = 24
1 u = 24 ÷ 12 = 2
Amount that Albert and Riordan shared
= 3 u + 2 u
= 5 u
= 5 x 2
= $10
Answer(s): $10
