Answer:
The formula for percent change is [tex]\frac{new-old}{old}(100)[/tex]. Because she scored 13 points and scored 22 points in the next game, the new value is 22 and the old value is 13. Plug in the values to get [tex]\frac{22-13}{13}[/tex] or [tex]\frac{9}{13}(100)[/tex]. Multiply the values to get 69.23 or 69.23%.
