y = 12x

Step-by-step explanation:

Given that:

y = cost of making a special order cupcake

A dozen of special order cupcakes = 12 pieces

Let the cost of extra ingredient for making a special order cupcake = x

Hence the cost y of making a dozen of such special order will be :

y = extra cost per order * number of orders

y = 12x
