Question

The cost of providing water bottles at a high school football game is $35 for the rental of the coolers and $0.50 per bottle

Answer 1

The cost function is an illustration of a linear function

The equation of the cost function is C(x) = 35 + 0.5x

The given parameters are:

$Rentals = 35$ -- the cost of renting a cooler

$Rate = 0.5$ --- the rate per bottle

Assume the number of bottles in a cooler is x.

The cost function for the bottles in a cooler would be:

$C(x) = Rentals + Rate \times x$

So, we have:

$C(x) = 35 + 0.5\times x$

Evaluate the products

$C(x) = 35 + 0.5x$

Hence, the equation is $C(x) = 35 + 0.5x$
