2. You are installing a new pre-constructed fence in front of your house. Each fence section measures 4 1/2 feet wide, and each end will also have a decorative piece that measures 1 3/4 feet wide.

Question

If the space for the fence is 30 feet wide, what is the most number of 4 1/2 foot fence sections you could install?

I calculated 4 1/2 + 3/4 = 5.25
30/5.25 = 4

Answer 1

Nope.

4.5x + 3.5 = 30

4.5x = 26.5

x = 5.89 = 5
