Answer :
Given:
Score in first game = 28 points
Score in second game = 35 points
To find his percentage increase, use the formula below:
[tex]\text{ \%increase=}\frac{New\text{ score - old score}}{\text{old score}}\times\frac{100}{1}[/tex]Input values into the formula above to find the percentage increase.
Thus, we have:
[tex]\begin{gathered} \text{ \%increase=}\frac{35-28}{28}\times\frac{100}{1} \\ \\ \text{ \% increase = }\frac{7}{28}\times\frac{100}{1}^{} \\ \\ \text{ \% increase = }0.25\text{ }\times\text{ 100 = 25\%} \end{gathered}[/tex]Therefore the percent of increase from the first game to the second game is 25%.
