Question

A pizza maker determined an annual profit in dollars

from selling pizzas using f(n) = 65n -0.04n where
n is the number of pizzas sold. What is the annual
profit if the pizza maker sells 300 pizzas?
$18,500
$3,600
$7,800
$15,900

Answer 1

If the number of pizzas sold is represented by n, the profit can be calculated by using the equation:

f(n) = 65n -0.04n

To find the profit from selling 300 pizzas, substitute n=300 into the equation:

f(300) = 65(300) - 0.04(300)

f(300) = 19500 - 12

f(300)= 19488

Therefore, the annual profit if the pizza maker sells 300 pizzas is $19,488.

Thus, the answer is not among the given options.

Answer 2

To find the annual profit from selling 300 pizzas, we need to substitute n = 300 into the profit function f(n) = 65n - 0.04n:

f(300) = 65(300) - 0.04(300)
f(300) = 19500 - 12
f(300) = $19,488

Therefore, the annual profit from selling 300 pizzas is $19,488. None of the given answer choices match this result exactly, but the closest option is D) $15,900.
