So, lets say it costs $1.25 per square yard to paint a wall. The wall is 18x25 feet.
How much will it cost to paint the wall.
First, I don't understand what is better. Converting 18x25 feet into yards which is (54x75) or converting down the cost from yard to feet which is aprox $0.416.
But lets say that it's better to convert feet to yards in this situation.
X is the cost.
But again. There are 3 feet in a yard, and it looks like that 9 is squared. But I fail to understand why it's that way.
Can anyone explain? Thanks!
