Question 201347
Spencer makes 9 out of 13 shots in the first half of a basketball game.
How many consecutive shots must he make in the second half of the game to
raise his percentage to 96%?
----------------
He's already missed 4.
96/100 = 96%, so he has to make the next 87.
----
The hard way:
(x+9)/(x+13) = 0.96
x+9 = 0.96*(x+13)
100x + 900 = 96x + 1248
4x = 348
x = 87
