An oven can cook 3 thin crust pizzas in an hour or 1 deep dish pizza in a hour. if you have one oven, how much time do you need to make 12 thin crust pizzas and 4 deep dish pizzas?

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5

the answer is:

mean: 6

mad: 2.14
