Question

Write a function rule for the total cost. One Burger Place sells burgers for $4.00 per patty and $0.75 per topping. Write a linear equation to show the total cost of a Burger.
Then calculate the total price for one burger with 1, 4, 6, and 10 toppings

Answer 1

y = total cost

x = amount of toppings

z = # of patties

y = 4z + 0.75x

For one burger with 1 topping, the equation becomes y = 4 + 0.75

1 topping: $4.75

4 toppings: 4 + (0.75 x 4) = $7

6 toppings: 4 + (0.75 x 6) = $8.50

10 toppings: 4 + (0.75 x 10) = $11.50
