Question

Rhea had a score of 70 on her first quiz and a score of 77 on her second quiz. What is the percent increase from her first quiz score to her second quiz score?

Answer 1

Answer:

10%

Step-by-step explanation:

77 - 70

|70|

× 100% =

7

70

× 100 = 10% (increase)

Where: 70 is the old value and 77 is the new value. In this case we have a positive change (increase) of 10 percent because the new value is greater than the old value.
