Question

How and his friends bought stickers for $1.25 each and will mark them up 180%. What will they sell the tickets for?

Answer 1

Answer:$2.25x

Explanation:

Lets use X to denote the amount of stickers How and his friends bought. so he buys them at 1.25x. An easy trick when doing percentages of a number is thinking of the percent as a fraction. So instead of 180, think of 180/100. Think of 1.25 as 125/100

multiply 180/100 by 125/100

you get 22500/10000 which equals 2.25

or 2.25x
