Distribution of blood pressure can be approximated as a normal distribution with mean 85 mm. and standard deviation 20 mm. A blood pressure of 125 or higher is considered high blood pressure. Approximate the percentage of people who have high blood pressure.

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

60: 45 =12: 9 =4: 3 so the answer is 4: 3

b is the correct answer
