The peak rate of a phone company is $.22 per minute, and the off-peak rate is $.11 per minute. Find the savings for a 16-minute phone call if it was made during off-peak time as opposed to peak time.

Round to the nearest hundreth.

peak: 16 x 0.22 = 3.52
off-peak: 16 x 0.11 = 1.76
3.52 - 1.76 = 1.76
therefore, he saved $1.76
The savings is (0.22 - 0.11) = 0.11 per minute. For 16 minutes that is 16*$0.11 = $1.76.
