A student got 70% on the first test
She got 77% on the second test
What is the percent increase ?
This was all that was given in question
what is (77-70)/70 x 100?
\
looks like ten percent increase. Teacher is too easy.
77 - 70 = 7
7/70 = 0.1 = 10% increase
To find the percent increase, we need to compare the difference between the two values to the original value.
First, let's calculate the difference between the two test scores:
Difference = Second test score - First test score = 77% - 70% = 7%
Next, we need to calculate the percent increase by dividing the difference by the original value and multiplying by 100:
Percent Increase = (Difference / First test score) × 100 = (7% / 70%) × 100 = 0.1 × 100 = 10%
Therefore, the percent increase is 10%.
