Question

Lupe needs to make a poster that is 2 m by 4 m for the big game. The cost of the paper is $1.75. Later she needs another poster with dimensions 1 m by 2 m. What is the paper for this poster likely to cost

Answer 1

$0.42

Explanation:

Given data

Dimension

Length=4m

Width=2m

Cost= $1.75

Area= 4*2= 8m^2

Cost per area=1.75/8

Cost per area=$0.21 per m^2

The new poster's dimension

Lenght =2m

Width= 1m

Area= 2*1= 2m^2

Hence if a square meter cost $0.21

Then 2 square meter will cost x

cross multiply

2*0.21=x

x=$0.42

Hence the new poster will cost $0.42
