Richard bought 3 1/4 ft of plumbing pipe. The pipe cost $1.60 a foot. How much did Richard pay for plumbing pipe?

A student solved the problem this way.

3 1/4 feet = 3.25 feet

Let n represent the amount Richard paid for plumbing pipe.

n = 3.25 * $1.60

n = $5.20

Richard paid $5.20 for plumbing pipe.
