Question 36685
Leila needs to make a poster that is 1m by 4.5m for the big game. the cost of the paper is $3.75. Later she needs another poster with dimensions 0.5m by 2.25m. What is the paper for this poster likely to cost?

The area of the 1st poster is 4.5 sq. meters; the cost is $3.75
The area of the 2nd poster is (0.5m)(2.25m)=1.125 sq. meters; the cost is "x"

Set up a proportion, as follows:
1.125/4.5 = x/3.75
x=0.9375 or approximately 94 cents
