Ricky is at the bakery shop when he sees that 8 pastries cost $160. he need 16 pastries. how much will 16 pastries cost?

16 pastries would cost the double cost of 8 pastries because 8 is half of 16

, if 8 pastries cost $160 then 16 pastries would cost $320.

You can multiply $160 by 2 because 16 is 8 * 2. 16 pastries would then be $320.

Or, you can divide $160 by 8, to get the price per pastry. You would get $20 per pastry, and multiply it by 16, which equals $320

(You would get the same answer either way)
