Question 1163076: Micbonne is studying the metabolic rate of rats and determines that, for every degree above room temperature (20˚C), 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.
