Answer:
40%
Step-by-step explanation:
So I mostly will focus on the jogging total hours because thats literally what it says lol. Anyways, here I used the percent equation, which is
___ is ___% of ___. Since the question is "what percent", we mark our blank percent part as x, and when I fill the equation in it will seem like this:
"20 is x% of 50 (total hours)". So, now I translate, and this means:
20=x50, or in other words, 20=50x. To get x alone we divide by 50, but we also do it for the 20. 20/50 is .4, but because it has to be a percent, we move the decimal 2 places to the right, which gives 40, and finally it becomes
40%.
Hope it helps

Okay from what I know that equation would basically be over one, on L'hopital's rule you take the derivative of the numerator and denominator to find the limit, if you take the derivative of 1 then you get 0 and the limit couldnt exist, so in this problem the limit does not exist :) <span />
Answer:
14.5x + 25
Step-by-step explanation:
note that (C + R)(x) = C(x) + R(x), thus
C(x) + R(x) = 2.5x + 25 + 12x = 14.5x + 25
