About 1/10 of the human population is left-handed.

If 1/10 of every person is left handed that means that 9/10 people would be right handed, so if 10% of people are left handed then the other 90% would be right handed. Hope this helped! :D

Step-by-step explanation:

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
