The Roaming Cell Phone Company charges $15.00 per month plus $0.20 per minute of airtime usage. The representative function for the situation is C(x) = 0.20x + 15, where C(x) represents total cost as a function of the minutes, x. What is the domain for the monthly charge and the airtime per minute?

• All integers greater than or equal to 0

• All real numbers greater than or equal to 0

• All real numbers

• All integers greater than or equal to 15

Zara made an initial deposit to a bank account and then added a fixed amount every week. The table shows the money in her account. Which statement could describe the relationship between the number of weeks and the balance in the account and does the relationship represent a function?

• The balance is 120 plus the number of weeks times 20. No, it is not a function.

• The balance is 120 plus the number of weeks times 20. Yes, it is a function.

• The balance is 120 times the number off weeks. No, it is not a function.
