Well the amount of toppings steadily increases with the cost of the pizza because at $12(I’m pretty sure it’s $12) u r at 0 on he toppings but at $14 u get 1 ,$16 u get 2,$18 u get 3, $20 u get 4, $22 u get 5, $24 u get 6,and so n and so on so u can see it cost $2 extra for each toppings and u base price ( original price for a the pizza with no toppings) is $12
