Question

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

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

Answer 1

The answer is B) 25%

Explanation:

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 you're finding the percentage of $200 to $150 and there's not much of a difference, so 25% is the correct answer.

Answer 2

200 - 150 = 50

so
50 / 200 * 100 = 25%

answer is B) 25%
