Selling price of a dozen brownies was $6 and markdown is $4.50.

Step-by-step explanation:

Florence Price's Brownies and More markdown all brownies by 75%.

New selling price of brownies after markdown becomes $1.5 of a dozen.

As we know markdown of price = New selling price - Old selling price

Let the selling price of the brownies were x before markdown.

Then markdown of the selling price will be = 0.75x

Now we will put values in the the given formula

0.75x = x - 1.5

x - 0.75x = 1.5 ⇒ .25x = 1.5

So the selling price of a dozen brownies was = $6

and markdown of a dozen = 75% of $6 = 6×0.75 = $4.5
