A company is selling books. It has to pay $500 to start printing the books, and once they have done that, the books sell at $14.99 each. How many books must they sell to make a profit?
First we would model an equation. X will be the amount of books sold, and Y will be profits (in dollars obv). They had to pay $500 before they could start selling, so we must account for that too.
This equation would be

because for every book sold, X increases by 1, increasing Y by 14.99
The answer would be 34 books sold in order to turn a profit. (500/14.99=
It appears that for every question missed, it deducts 3 points.
so if Julie missed 6 questions, then she received a : (-3 * 6) = -18
Answer:
Population (p) = 4,000 hundred metric tons
Size of the yield (f(p)) = 8,000 hundred metric tons
Step-by-step explanation:
The population of sardines 'p', for which the derivate of the function f(p) is zero, is the population that gives the maximum sustainable yield:

The size of the maximum sustainable yield is:

Population = 4,000 hundred metric tons
Size of the yield = 8,000 hundred metric tons
