Question

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

Answer 1

Answer:

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

Step-by-step 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 $\frac{225-120}{120}$ * 100% = $\frac{105}{120}$ * 100% = 0.875 * 100% = 87.5%, so the correct answer is a percent change of 87.5%.

Answer 2

Answer:

$53\frac{1}{3}$ %

Step-by-step explanation:

$\frac{120}{225} =\frac{y}{100}$

225 × y = 120 × 100

225y = 12000

225y ÷ 225 = 12000 ÷ 225

$y=53\frac{1}{3}$
