A basketball player has made 21 of her last 30 free throws a percentage of 70, how can you model the player's free throw percentage as a rational function

For this case what you should do is write the following function:

y = (a / b) * 100

Where,

A: amount of successful free throws

B: total amount of free throws

Substituting values we have:

y = (21/30) * 100

The result is:

Y = 70% (as we expected)

Answer:

a rational function that can model the player's free throw percentage is:

y = (21/30) * 100
