Step-by-step explanation:

A function is represented by every input has only one output. Let’s look at each of the answer choices:

A. Input 4 notebooks, cost is $20 and input 5 notebooks, cost is $25. This is a function

B. Input 1 hour, charge is $20 and input 2 hours, charge is $40. This is a function

C. Input 1 hour, drove 50 miles and input 2 hours, drove 100 miles. This is a function.

D. Input 6 gum balls chewed, chewed in 2 and 3 hours. This is NOT a function. The input does not have only one output.

I hope this helps! :)
