Each year, Terrell buys a plane ticket to visit his grandmother for a week. Last year, he paid $130. This year, he paid $143. What was the percent increase in the cost of his plane ticket? Show your work.

that is the question this is my answer: amount of change/original amount = percent of change/100 143/130 = x/100 143 x 100 = 14,300 130 x 1 = 130 so we now have the fraction 14,300 over 130 which reduces to 110 over 1 which is actually just 110. So x = 110. Our percentage increase is 110.

amount of change = (new amount - original amount)
