Olivia's power went out at midnight. She knows that during a power outage, it is important to leave the freezer and refrigerator doors closed. This keeps the food inside at a safe

The temperature inside Olivia's freezer t hours after midnight can be modeled by the equation T-70-700-005, where T is the temperature in degrees Fahrenheit.
