Last year, Nick went bowling several times and earned an average score of 82 points. This year, after taking a class at school, he improved his score
to an average of 123 points. What is the percent of increase in Nick's
average score? *

150%

Explanation:

1. Turn it into a fraction. (123/82)

2. Divide the numerator (123) by the denominator (82). (123÷82=1.5)

3. Multiply the decimal (1.5) by 100 and add “%” at the end to make it a percentage. (1.5x100=150)(150=150%)
