You buy 10 vegetarian pizzas and pay with $100. How much change do you receive?

Answer 1

Change back = $100 - (10 x price of 1 veggie pizza in dollars), if a single pizza (plus tax and tip) costs less than $10.

If a single pizza costs exactly $10 (including tax and tip), you get no change back.

If a single pizza costs more than $10, you cannot buy 10 with only $100.
