Anisa is cooling water in her fridge. the waters temperature starts at 85 degrees and she cools it 3.5 degrees every minute for 12 minutes. create a number sentence to model this scenario.

The temperature starts at 85 degrees.
t = 85

After 1 minute, it loses 3.5 degrees.
t = 85 - 3.5

After 2 minutes, it loses another 3.5 degrees.
t = 85 - 3.5 * 2

After 3 minutes, it loses another 3.5 degrees.
t = 85 - 3.5 * 3

etc.

After 12 minutes, it loses another 3.5 times 12 degrees.
t = 85 - 3.5 * 12
