Ms. Law is on leave from work and she has a savings account. She is not getting any extra income and her bills are $899 a week. Her account can be represented by the following equations

y = 11,000 - 899x

where x is the number of weeks and y is the amount left in the account. What is a reasonable domain for this situation?

• {0, 1, 2, 3, 4, 5}

• {11000, 10911, 10822, 10733, 10644, 10555}

• 0 ≤ x ≤ 5

• 10555 ≤ f(x) ≤ 11000

Oceanside Bike Rental Shop charges 16 dollars plus $8.36 an hour for renting a bike. Write the equation that represents the total cost, C, in terms of the number of bike rental hours, h, purchased.

• C = 8.36h + 16

• h = 8.36C + 16

• C = 16h + 8.36

• h = 8.36C + 16
