Can someone please help me with this question. Thank you!

The information in the table represents the temperature of a cup of hot chocolate in relations to time.

Time(t) Temperature(T)

0 60

5 54

10 48

15 44

20 41

Use the exponential regression function in your calculator to find the equation in the form T=a(b)^t, where t=time(min) and T=termperature (*C), a and b to the nearest hunderedth. Then use the formula derived in the first question to determine the temperature of the hot chocolate at t=35 minutes.
