$12 each. Write a linear model that represents the total cost of
a birthday party y as a function of the number of guests x.

Respuesta :

A linear model that represents the total cost of  a birthday party is y = $125 + $12x

Linear models

A linear model consists of one variable raised to the power of 1.  An example is x + 2

Fixed cost and variable cost

The cost of the birthday party is the fixed cost. This cost remains constant regardless of the number of guests. The fee per guest is the variable cost. It increases with the number of guests.

Derivation of the equation

Total cost = cost of the birthday party + (cost per guest x number of guests)

y = $125 + $12x
