divide the number of baskets she makes by the number of shots she takes and see if you get 0.9

Answer 5

Solve the following for x\[\frac{2+x}{10+x}\text{= }0.9 \]\[x=70 \]The total shots thrown is 80 to reach the 90% average or 70 shots after the first 10 shots.

Answer 6

Yes, x is 70, but I think the question is asking for the _total number_ of shots. It is a little ambiguous though.
