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
