Answer:

If double cheese is charged 5% more on a pizza costing 480, then we need to find the amount of the additional charge.

First, we can calculate 5% of 480 as:

5/100 x 480 = 24

This is the total increase in price if the pizza had no cheese on it. However, we are only interested in the increase in price due to double cheese, which is 5% more than the price with no cheese.

To find the price of the pizza with double cheese, we need to add 5% of the original price to the original price:

480 + 5/100 x 480 = 480 + 24 = 504

So the price of the pizza with double cheese is 504.

The additional amount charged for double cheese is therefore:

504 - 480 = 24

So the additional amount charged for double cheese is 24.
