Tana bought $74.12 worth of CDs @ a music store. Since she is an employee of the store she received a 19% discount. What was the actual price of the CDs she bought before the discount?

The $74.12 she paid was 81% of the retail price (the price before the discount was taken). So the equation is: $74.12=.81 x (retail price). Therefore: $74.12/.81 = retail price, so the retail price was $91.51.

since she gets a 19% discount, that means the $74.12 will be 81% of the original price...so algebraeically, we can say the following:
0.81x = 74.12
where 0.81 = 81/100
and x = original price...any number as it is an unknown.
we can then rearrange the statement to find x by isolating it on one side and all the numbers on the other side giving:
x = 74.12/0.81
stick it in the calculator (or work it out all by hand)...and you'll get $91.51 in 2 decimal places. (gosh...she spent so much on CD's...i wonder what she really bought...lol...and GOSH! look how much she saved!)

If discount is 19%, $74.12 is 81% of x
1% = 74.12 ÷ 81 = 0.915
x = 0.915 x 100 = 91.5.
Price before discount = $91.50

Set up an equation:
74.12 = (100-19)% of x
74.12 = 81% of x
74.12 = .81 * x
Now solve for x:
x = 74.12 / .81 which is about 91.51

0.81X= 74.12 so that means divide 74.12 by 0.81 (Which is 100% minus the discount)

The answer is $88.20. This was very easy if you need to show your work it is $74.12 + 19%= $88.20

.19x = 74.12 just simply divide both side by .19
