Question

help need answer to this math proplome!
Each year, Terrell buys a plane ticket to visit his grandmother for a week. Last year, he paid one hundred thirty dollars. This year, he paid one hundred forty-three dollars. What was the percent increase in the cost of his plane ticket? Show your work.

Answer 1

If x is the original cost and y is the new cost, then (y-x)/x times 100 is the percentage increase.

Answer 2

so just - them and times the left overs by 100 to get the answer

Answer 3

sort of...

percent change is equal to (new price - old price) / (old price)

so it would be like (143 - 130)/130

Answer 4

Don't forget my divisor.

Answer 5

it's easier to see with small numbers... if you pay $10 today, and $15 tomorrow, the percentage increase is (15-10)/10 = 5/10 = 50%... makes sense, if you think of it... you paid $5 more tomorrow, and $5 is half or 50% of $10.

Answer 6

ok so 13x 100= 130 so thats the answer

Answer 7

no, you're missing the step where you divide by the original price.
