Question 10 • Grade 7 Mathematics

Lonnie threw 50 free throws and missed 16 of them. If Lonnie throws 75 free throws, what can be predicted about the number she will make successfully?

Answer
A
Lonnie will make 59 free throws.
B
Lonnie will make 24 free throws.
C
Lonnie will make 66 free throws.
D
Lonnie will make 51 free throws.

Explanation

Lonnie made 50 − 16 = 34 free throws, so her success rate was 34/50 = 0.68. At that rate, she would be expected to make 0.68 × 75 = 51 free throws, so the prediction is that she will make 51.
