Problema Solution
Find the cost of framing a rectangular picture with dimensions of 8 inches by 10 inches if framing material costs $0.75 per inch.
Answer provided by our tutors
first lets calculate the length of the frame needed
the length of the frame L = the perimeter of a rectangle with dimensions 8 in and 10 in
L = 2*(8 + 10)
L = 36 in
we have the following proportion
$0.75 per in = $x per 36 in
0.75 : 1 = x : 36
x = 0.75*36
x = $27
the cost of the framing material is $27.
