Igor, on the varsity basketball team, has made 36 of his 80 foul shots so far this season. What is his percent accuracy? How many foul shots must he make in a row to bring his average up to 50%?
Igor�s percent accuracy is 36/80 = .45 = 45% so far.
Let’s have him make x more shots:
2(36 + x) = 1(80 + x)
72 + 2x = 80 + x
So x = 8.
Now, can he do it? The pressure is building.
