At the moment a hot cake is put in a cooler, the difference between the cake's and the cooler's temperature is 50° Celsius. This causes the cake to cool and the temperature difference loses 1/5 of its value every minute.

Write a function that gives the temperature difference in degrees Celsius, D(t),t minutes after the cake was put in the cooler.

Step-by-step explanation:

We are given that

Initially the difference between the cake's and the cooler's temperature ,a=50 degree Celsius

We have to find the function that gives the temperature difference in degrees Celsius D(t).

We know that

Substitute the values

This is required function that gives the temperature difference in degrees Celsius.
