Let x be the original price. The discount on this item is 64% of x, that means:
discount = x(0.64) = $30, x = 30/0.64 = original price x = $46.875:
Write an equation:
NET PRICE = Original price - discount (on the original price)
NET PRICE = x - 0.64.x or NET PRICE = x(1-0.64)
NET PRICE =0.36.x

Answer:
Sets
Step-by-step explanation:
1) Set can be defined as a collection of objects that are well defined and distinct.
2) Since each idea has its own unique value or characteristic, they can be considered as objects.
3) Thus, a collection of ideas can be considered as a set.
4) In this case we would define the null set as the set with no ideas.
5) The sets can be represented with the help of curly brackets { }.
6) We can represent it in the set form as:
{Idea 1, Idea 2, Idea 3, Idea 4,...}
7) It can be considered a countable set as we can always count the number of ideas.
8) It is a finite set.
