Original price: $29.99; markdown: 33 1/3% find the retail price

Retail Price of the item is $ 19.99 (approx.)

Step-by-step explanation:

Given:

Original Price of an item = $ 29.99

Markdown Percentage = % = %

We need to find: Retail Price

We know that Retail price = Original Price - Markdown amount

Markdown amount =

                               =

                               =

                               = $ 10 (approx.)

So, Retail price = 29.99 - 10 = $ 19.99

Therefore, Retail Price of the item is $ 19.99 (approx.)

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
