Question 1163076: Micbonne is studying the metabolic rate of rats and determines that, for every degree above room temperature (20ËšC), the rats burn an extra rate, and their normal metabolic rate is directly proportional to their weights, represented by w, in grams.. If the number of calories burned by a rat, E, when the temperature, t, is at or above room temperature is given by the equation E = (0.017w)t + (t-20)(0.017w + 3)t, which of the following statements is true?
A) The number of calories a rat burns per hour at room temperature is 0.017.
B) At 20 degrees Celsius a rat burns 0.017 calories per gram of body weight per hour.
C) A rat that weighs 100 grams will burn 17 calories per hour.
D) The base metabolic rate of a rat is 20 calories per hour.

when t=20
the terms after the + sign are 0
E=0.017*100*20=34 cal/hour
So at 20 C a rat burns 0.017 cal/gm body weight per hour.
B
