Question

Once upon a time I weighed 120 pounds. Now I weigh 225 pounds. What is the percent change?

Answer 1

`53(1)/(3)` %

Explanation:

`(120)/(225) =(y)/(100)`

225 × y = 120 × 100

225y = 12000

225y ÷ 225 = 12000 ÷ 225

`y=53(1)/(3)`

Answer 2

The percent change is 87.5%. (You're one chonky boi lol)

Explanation:

To find the percent change, calculate the difference between the new weight and the old weight and divide that value by the old weight and multiply by 100% to find the percent change. In this case, the equation would be
`(225-120)/(120)` * 100% =
`(105)/(120)` * 100% = 0.875 * 100% = 87.5%, so the correct answer is a percent change of 87.5%.
