My last one.

A person's metabolic rate tends to go up after eating a meal and then, after some time has passed, it returns to a resting metabolic rate. This phenomenon is known as the thermic effect of food, and the effect (in kJ/hr) for one individual is
F(t) = -10.28 + 175.9te^-t/1.3 where t is the number of hours that have elapsed since eating a meal. Find the total thermic energy of a meal for the next four hours after a meal by integrating the thermic effect function between t = 0 and t = 4.

The answer I got is 150.1 kJ, IS IT RIGHT? I just need a yes or no and I can figure out what I did.
 
my calculator sez a liitle over 200 kJ

confirm your integral ...

\(\displaystyle \int_0^4 -10.28+175.9te^{\frac{-t}{1.3}} dt\)
