= 47 students
100 + 0.50c = 1.50c <== ur equation
100 = 1.50c - 0.50c
100 = c....so he would have to sell 100 cups of coffee to break even
has no antiderivative in terms of elementary functions (polynomials, exponentials, logarithms, trigonometric functions, etc), but there is a special function defined to fit that role called the error function,
, where

By the fundamental theorem of calculus, we can see that

which means we have

Answer:
5.507*10^-7%
Step-by-step explanation:
(2.5 * 10^5)/(4.54 * 10^9)*1/100 %= 5.507*10^-7%
