1. ## Mathematics wizard ?

I can't figure this out. I'm selling some items for \$120. Original cost was \$1200, what is the percentage of saving and how did you figure it out.

2. The saving is 90%
There are two ways to calculate it:

1. Selling price / original cost x 100 = Percentage of original price:
(120 / 1200 x 100 = 10%), i.e. the selling price is 10% of the original cost, so 100% - 10% = 90% saving.

2. (Original cost - selling price) / original price x 100 = %saving
((1200 - 120) = 1080.
1080/1200 x 100 = 90%

3. 90% savings

Original price \$1200
Subtract selling price \$120 = \$1080
Divide the differnce between the two by the original price 1080/1200= .9
Multiply .9 by 100 to convert to a percentage. .9 x 100 = 90%

*sorry TheeVillageIdiot I didn't see your post until after I posted mine.

4. Thank You for the answers. I knew it was 90% but was stumped on how to do the math. BTW Alexa is a dumb ass.

She can't be any dumber than my dear Siri!

6. I just tested the insults on my dear Alexa and she very calmly referred me to the feedback section on the Alexa app, without even the tone she often gets when I asked her the same question several times.
