**Examples**

A plumber needs to install a sink using pieces of pipe measuring inches, inches, inches and inches. Find the total length of the pipe needed to cut all the pieces.

**Solutions 1**

Since we are finding a total, we use addition:

The plumber would need a piece of pipe at least inches long.

**Example 2**

It takes Bill hours to cut a lawn. It takes Walter hours to cut the same lawn. How much faster is Bill?

**Solution 2**

Since we are looking for a difference, we subtract:

**Example 3**

How much will a trip of 212 miles cost if the allowance is cents per mile?

Hence the allowance for the trip is $58.83.

**Example 4**

How many cubic feet will a 240-gallon tank hold if one cubic foot of water is about gallons?
