Answer 2

Hello!

The answer is:

The percent increase from her first quiz score to her second quiz score is 10%.

Why?

To know what is the percent increase from her first quiz to her second quiz, first we need to calculate the increase points, then, represent it in porcentage value.

Then, calculating her increas in points, we have:

`Increase=SecondQuizScore-FirstQuizScore\\Increase=77points-70points=7points\\Increas=7points`

Now, calculating the percent increase, we have:

`Increase(Percentage)=(Increase(points))/(FirstScore)*100\\\\Increase(Percentage)=(7)/(70)*100\\\\Increase(Percentage)=0.10*100=10`

Hence, the percent increase from her first quiz score to her second quiz score is 10%.

Have a nice day!
