When the price dropped $0.05 per gallon, Mr. LEe paid $22.68 for the 14 gallons of gas. To the nearest percent, by which percent did the price per gallon change?

Answer provided by our tutors

The new price per gallon is: 22.68/14 = $1.62 per gallon.

The old price per gallon was: 1.62 + 0.05 = $1.67 per gallon.

The price changed by 0.05 or in percentage:

0.05/1.67 = 0.0299 or by 3% to the nearest percent.
