Problema Solution
we used 5 1/2 inches of wrapping paper.It costs $2.25 for 1 square foot and a $3.00 service fee.How much will it cost for 5 1/2 inches of wrapping paper? Hint (1 square foot is 144 inches)
Answer provided by our tutors
Assuming 1 ft^2 = 144 in^2 and that the area of the wrapping paper used is 5 1/2 in^2 we have:
1 in^2 = 1/144 ft^2
5 1/2 in^2 = 5.5 in^2
5.5 in^2 = 5.5/144 ft^2
1 ft^2 costs $2.25 meaning 5.5/144 ft^2 will cost:
(5.5/144)*2.25 = $0.086
$0.086 + $3.00 = $3.086
