When the internal body temperature increases by 33°F, there is an increases in BMR (Body metabolic rate) by 7%.
Mark has a BMR of 2,200 calories
Mark has a fever of 99.6ºF
increase in body temperature = 99.6/33 = 3.02
now percentage increase in BMR = 3.02 x 7 = 21.14% = 0.2114
increase in BMR = 2200 x 0.2114 = 465.08
His BMR now would be = 2200 + 465.08 = 2665.08
