Okay, now what can you do to work out how much an 18 inch pizza costs, based on how much the 1 inch pizza costs?

anonymous · Answer

its 1.5 for each inch
but wen i multiply 1.5 x 12 i get 18 not 8

anonymous · Answer

Take a look at what numbers you are dividing to find the price per inch.

anonymous · Answer

cuz i divided 12 by 8 and got 1.5 so i assumed that 1.5 is how much per inch and so wen i  multiplied 1.5 x 12 i got 18

The pizza is 12 inches, and it costs 8 dollars. You need to divide the number of inches by the amount, so 8/12.
