Marked at half price and less the dealer discount of $1.50, the video cost $4.50. How much was the original price of the video?

$15

Step-by-step explanation:

Given data

let the original price be x

we are told that the discount is $1.50

Therefore the original price is the summation of the discount, the current price and the and the marked half price

Hence the price = 1.5+4.5+ 4.5*2

=6+9

=$15

Hence the original price is $15

multiple all that

step-by-step explanation:

27×17

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
