Question

Mateo has been studying after school while preparing for a test retake. His work paid off ! His score on the retake was a 94. This was quite a difference from the grade on his first attempt which was a 68. What is the approximate percent of change between the two tests?

Answer 1

increase of 28?

Explanation:

Okay so, I believe it is 28, let me explain. First, work out the difference (decrease) between the two numbers you are comparing. Next, divide the decrease by the original number and multiply the answer by 100. If the answer is a negative number, this is a percentage increase.

Answer 2

28%

Explanation:

We know that 100 percent is total. Mateo first scored 68/100, then a retake got his score up to 94/100.

First, subtract the two numbers

94 - 68 = 26

Put 26 over 94 to make this 26/94

Divide to get 0.28 (simplified and rounded)

So the increase was 28%
