Problema Solution
A group of high school students is making a parade float by stuffing pieces of tissue paper into a wore frame. They use 150 tissues to fill an area 3ft long and 2ft wide. The total area they want to fill is 8ft long and 7ft wide. What is the total number of tissues they will need?
Answer provided by our tutors
150 tissues are needed to fill and area of 3x2 = 6 ft^2
'x' tissues are needed to fill an area of 8x7 = 56 ft^2
Since the number of tissues is directly proportional to the area we have:
x : 56 = 150 : 6
x = (150*56)/6
x = 1,456 tissues
The total number of tissues they will need is 1,456 tissues.
