When we select r things from n things in a order , we use permutations.

Formula for permutation:  ^nP_r=\dfrac{n!}{(n-r)!}

Given : The number of family members who are potential kidney donors. = 9

A store is having 20% off sale. If the reduce price is 90.40, what is the original price
ipn [44]
In order to find the original price, we need to divide by 4. This is because the price was reduced by 20%, it is 4/5 of the original price. 

By dividing by 4, we can see that 90.40 is 22.60. 

To find the original price, we add 22.60 (1/5 of the original price), to 90.40 (4/5 the original price) to find that $113 is the original price.
