The cost c (in dollars) for the fuel and maintenance of a go-cart is given by c=10x+900, where x is the number of rides. It costs $25 per ride. How many rides does it take to break even?

Respuesta :

Answer

As per the statement:

The cost function is given by

[tex]c(x) = 10x+900[/tex]

where

x represents the number of rides

c(x)  represents the total cost including the fixed cost.

It is also given that it costs $25 per ride.

so,

Revenue function for x number of rides be;

[tex]R(x) = 25x[/tex]

For break even:-

The cost must be equal to the Revenue i.,e

[tex]c(x) = R(x)[/tex]

[tex]10x+900 = 25x[/tex]

Subtract 10x from both sides we have;

900 = 15x

Divide both sides by 15 we get;

60 = x

or

x = 60

Therefore, 60 rides does it take to break even.
