I think this is a Newton's Law of Cooling question but the formula I have for that isn't working...

A pizza, heated to a temperature of 350 degrees Fahrenheit, is taken out of an oven and placed in a 75 degrees Fahrenheit room at time t=0 minutes. The temperature of the pizza is changing at a rate of -110e^-0.4t degrees Fahrenheit per minute. To the nearest degree, what is the temperature of the pizza at

time t=5 minutes?

The formula I tried to use was T= (To - Ts)e^kt + Ts

The problem I'm having is with the "changing at a rate of..." I don't know what to do with that information. I'd really appreciate the step by step of how to do this particular question.

Thank you!
