Question

The cost for a pizza at Pizza Palace depends on the size of the pizza and the number of toppings for a large pizza the cost in dollars, C, with t numbers of toppings can be determined with the equation C = 2 t + 18 what does 2 represent in the equation

Answer 1

C = 2 t + 18

This equation satisfy the general formula from a linear model:

`y= mx +b`

Where m represent the slope and b the intercept.

And for this case the number 2 represent the slope for the model and is telling to us that if we increase the number of toppings by 1 unit we would expect an increase in the cost of 2 dollars.

The 18 is a fixed cost and represent the intercept for the model

Explanation:

For this case we know that the cost in dollars, C for a pizza based, with t numbers of toppings can be determined with the equation

C = 2 t + 18

This equation satisfy the general formula from a linear model:

`y= mx +b`

Where m represent the slope and b the intercept.

And for this case the number 2 represent the slope for the model and is telling to us that if we increase the number of toppings by 1 unit we would expect an increase in the cost of 2 dollars.

The 18 is a fixed cost and represent the intercept for the model
