option: D is correct. (  (D) a markup of 15% on selling price is equivalent to a 85% markup on cost ).

Step-by-step explanation:

" Markup is the percentage difference between a product's cost and its selling price "

Since we are asked to Convert a markup of 15% on selling price to its equivalent markup on cost.

As there is a markup of  15% on selling price. Hence the cost of the product would be (100-15)%=85% of the selling price.

Hence, a markup of 15% on selling price is equivalent to a 85% markup on cost.

Hence, option D is true.

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.
