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:

(36 +

2(36 +

72 + 2

So

*x*) / (80 +*x*) = 50% = .50 = 1/22(36 +

*x*) = 1(80 +*x*)72 + 2

*x*= 80 +*x*So

*x*= 8.Now, can he do it? The pressure is building.
