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?
Let the total cost = C
Caleb contributes (8/13) C
Paul contributes (8/13)C - 6
(8/13)C + (8/13)C - 6 = C
(16/13)C - C = 6
(3/13)C = 6
C = 6 (13/3) = $26
Caleb contributes (8/13)(26) = $16
Paul contributes 16 - 6= $10
