Katie makes 65% of her shots from the free throw line. Can you determine how many consecutive free throws she must make in order to increase her percentage to 68%? Explain.

Answer 1

no
if she made 65 out of 100 that will take less than if she made 650 out of 1000

Answer 2

Hard to say. If she has made 65% of n throws so far, then she needs to throw x more in a row to get to 68%.

.65n + x = .68(n+x)
.03n = .32x
x = 3/32 n
