Question

A large pizza costs $10. Each topping costs an additional $2. Let x represents the number of toppings and y represents the total cost. What the equation for the relationship?

Answer 1

y=2x+10

Explanation:

since we don't know how many toppings they're getting, the x is there to represent the number of toppings. The $10 will stay the same because it's the base amount, and the y is the base amount plus the number of toppings.

Sorry if that's confusing, hope this helps :)
