Abicycle manufacturer uses the given expression to model the monthly profit from sales of a new model of bicycle, where x is the selling price of one bicycle, in dollars. at what selling prices for the bicycle will the manufacturer make neither a profit nor a loss?

The manufacturer will have no profit or loss when the selling price equals $200 or $100.

Step-by-step explanation:

The expression to model the monthly profit from sales of a new model of bicycle is

-x^2 + 300x -20,000

Let

f(x) -----> the monthly profit in dollars

x -----> s the selling price of one bicycle in dollars

we know that

The manufacturer will make no profit nor a loss when the profit is equal to zero

so

f(x)=0

Multiply by -1 both sides

The formula to solve a quadratic equation of the form is equal to

in this problem we have

substitute in the formula

therefore

The manufacturer will have no profit or loss when the selling price equals $200 or $100.

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value
