A pizza maker determined an annual profit in dollars from selling pizzas using `f\left(n\right)=65n-0.04n^{2}`where `n` is the number of pizzas sold. What is the annual profit if the pizza maker sells 300 pizzas?

Question

A- $18,500
B- $3,600
C- $7,800
D- $15,900

Answer 1

To find the annual profit when selling 300 pizzas, we need to plug in `n = 300` into the profit function `f(n) = 65n - 0.04n^2`.

So, `f(300) = 65(300) - 0.04(300)^2`
`f(300) = 19500 - 0.04(900)`
`f(300) = 19500 - 36`
`f(300) = 19464`

Therefore, the annual profit if the pizza maker sells 300 pizzas is $19,464 which is not one of the given options.
