What was the percent decrease in Jerry's score?
A. 2.11%
B. 1.74%
C. 17.4%
D. 21.1%

Answer 1

C because new - original / original, So 190 - 230/230 = -40/230 = 17.39.... so 17.4%

Answer 2

To find a percent change do this:
1. Subtract the new number minus the old number.
2. Divide the difference by the old number.
3. Multiply by 100.
If the answer is positive, it is a percent increase.
If the answer is negative, it is a percent decrease.
