Each year, Terrell buys a plane ticket to visit his grandmother for a week. Last year, he paid one hundred thirty-five dollars. This year, he paid one hundred eighty-nine dollars. What was the percent increase in the cost of his plane ticket? Show your work.

OpenStudy (barrycarter):

189-135 = 54 dollars more. 54 dollars is 54/135 % of 135 dollars or 40% more.
