caleb and paul bought a gift for their younger sister. caleb contributed 8 dollars for
every 13 dollars the gift cost. overall, paul contributed 6 fewer dollars than caleb. what was the cost of the present?
Caleb contributes (8/21) of the cost of the gift
Paul contributes (13/21) of the cost of the gift
So
(13/21)C - (8/21)C = 6
(5/21)C = 6
C = 6 (21/5) = $25.20
8 - 6 = 2
13 * 2 = 26
26 was the cost
