Question

Last year, Abe went bowling several times and earned an average score of 90 points. This year, after taking a class at school, he improved his score to an average of 99 points. What is the percent of increase in Abe's average score?

a) 5%
b) 9%
c) 10%
d) 10.1%

Answer 1

The percent increase in Abe's average score is 10%.

Step-by-step explanation:

To find the percent increase in Abe's average score, we need to calculate the difference between his scores and then divide it by his initial average score.

The difference between his scores is 99 - 90 = 9.

To find the percent increase, divide 9 by 90 and multiply it by 100:

(9/90) * 100 = 10%
