Question

.
A plain hamburger costs $6.00. Each additional topping costs $2 each.
Which linear equation BEST models the cost of the hamburger, y
, based on the number of toppings,
?

Answer 1

Let x = number of toppings and y = total cost (dollars).
The cost is the $6 base plus $2 per topping, so

y = 6 + 2x

(or y = 2x + 6).
