Hello!,

FRIST :  2 topping - $14 
1 topping - $10 

1 topping is $4. (You find the difference between the two.) 
That means that a medium pizza, with no toppings is worth $6. 
So for a large plain cheese pizza - 
$6.00/10x8 [80%] 
= 2.40 
So, a large cheese pizza would cost [$6.00+$2.40] $8.40. 

I wouldn't think there would be a difference in the surcharge for a toppings. But! 
1 topping is $4. 
4/10*8=0.4 
So the large topping would cost [$4.00+$0.40] $4.40 THANK YOU!
