# How To Calculate Sale Items?

\$120 on sale for 25% off = \$90 Final price

120 x .25 =30.00 \$120-\$30.00= \$90.00

Well, you have to set up a proportion. If you wanted to find out 25% of \$120, you set up something that looks like x over 120 is equal to 25 over 100.
So then you multiply x times 100 and set it equal to 25 times 120. Then you divide by 100 and subtract the answer you get from 120.

The cost is of 150\$. 25% of 120 is 30.

So add it in 120, you got 150 in total.

No...if the sale price is 120 and you want to know the real price then you know 120 is 75% of the real price so all you do is
120/75
=1.6
1.6 x 100
= 160

If 120 was the final price and you wanted to know 75% of this, same concept reversed

120/100
=1.2
1.2 x 75
=90

:-D hope i helped

easiest way to do it is 120 x .75
or in other words 120 x 3/4
which comes to be 90.
the .75 is just 100 - 25, or 100% (the original price) minus 25% (the discount), 75%

I multiply by 10%and for each 10% say an item is 35 % off of 50.00, 10% of \$50.00 is \$5.00 make that 3X10%=\$15.00 and 5% is half of !0% which is \$2.50. \$15.00 + \$2.50 is \$17.50 off of \$50.00 or \$50.00 - 17.50 = \$32.50
