Answer:

90 degrees

Explanation:

The question asks for the temp after an hour and a half. This is the same as 90 minutes. With this, you plug 90 in for t.

This is what it looks like:

T(t)=69e^-0.0174(90) + 76

Then you solve for T(t)

T(t)=69e^-1.566 +76

T(t)=69(0.2088) +76

T(t)=14.41265 +76

T(t)=90.41265

Then round to 90 degrees
