The owner of a sportin goods store buys pairs of rollerblades for $60 and marks them up 25%.several months later, he decided to clear his inventory and sells each pair of rollerblades at a discount of 20%.what is the total price of a pair of these roller blades with the discount and a 6% sales tax?

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%
