Howie · Answer 1

C is the correct answer.

Maxim Burton · Answer 2

C. Number of games; total cost; 4 to 8 games; $10 to $20.

Step-by-step explanation:

Since the number of games played affects the total cost, # of games is the independent variable (domain) and total cost is the dependent variable (range). There are 4 people in total and they plan to bowl 1 to 2 each, resulting in a total of 4 to 8 games. 2.50 dollars times 4 is $10 and 2.50 dollars times 8 is $20.
