Lucky's Market purchased a new freezer for the store. When the freezer door stays open, the temperature
inside rises. The table shows how much the
temperature rises every 15 minutes. Find the unit rate.
temperature (°F) =10
number of minutes =15
°F per minute

The rate of change is 2/3 Fahrenheit  per minute

Step-by-step explanation:

Let's say x is the number of minutes and y is the temperature.Now we could set up a proportion to solve for the temperature for every per minute.

15x = 10

x =

x =

1. d.90

2. e. none of these (80)

3. a. 0

4. b. 6

5. e. none of these (10)

6. a. 5

y + 11 = (1/4)(x + 16)
