If the price of a yo-yo in a shop increased by 20% and is now $18.00, what was the original price?

So $18 would be 120%. This is because the yoyo is 100% and you increased by 20%. If this was a calculator question, you would do 18 / 120 than times by 100 to get 100%. Naturally it would just be 18/12 x 10 = 15. so $15 is 100% or the originally price.

Hope it helped :)

no, x cannot be the same number. in all of them, x is 1. for one input there is another output. g is not a function

typically if you want , you would actually put questions here for us to you. but hey, that's just me. maybe someone will magically answer the questions for you without knowing what they are.
