Newton's Law of Cooling Question

A pizza, heated to a temperature of 350 degrees Fahrenheit is taken out of an oven and placed in a 75 degree 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?

I am not sure if I simply have to substitute in the time of 5 minutes and add it to the original temperature of 350 degrees, I've never done a question like this before. Could anyone help me out?
