Question

The price of a calculator has decreased from $200 to $150. What is the percentage of decrease?

A) 3%
B) 25%
C) 33%
D) 50%

Answer 1

Answer; B / 200-25%=50

Answer 2

B) 25%
If half of 200 is 100 (50%) and you're trying to find out what 150$ is equal to from the decrease rate, you divide 50 in half because youre finding the percentage of $200 to $150 and there's not much of a difference, so 25%.
