Iwant to buy a book that is on sale with a 50% discount. if the sales price is $25. what was the original price?

The original price is $50.

Step-by-step explanation:

First, convert the 50% to a real mathematical number. For percents, this is always done by dividing the 50% by 100%, or 50% / 100% = 0.500.

Second, find out what 50% of $50 is. This is the amount of the sale discount. This is always found by multiplying 0.500 by the item's cost $50, like this:

0.500 x $50 = $25.00.

So for this sale, you'll save $25.00 on this item.

This means, the cost of the item to you is

$50 - $25.00 = $25.00.

hopefully my answer helps! ♡

if my answers helped you please tell me, therefore I know.. that I did them correctly or incorrectly. anyways, have a great day/night!

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
