15 Howard's share : Total share = 1 : 5
The total amount paid for the gift is repeated. Make the total amount the same. LCM of 10 and 6 is 30.
Amount that Tom, Elijah and Cody paid = 25 u
Amount that Tom and Elijah paid
= 25 u - 9 u
= 16 u
The amount that Tom and Elijah each paid is the same.
Amount that Tom and Elijah each paid
= 16 u ÷ 2
= 8 u
Cost of the gift = 30 u
30 u = 90
1 u = 90 ÷ 30 = 3
Amount that Elijah paid
= 8 u
= 8 x 3
= $24
Answer(s): $24
