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 :)
The original price was $15.00
The price of the yo-yo increased by 20% and went to $18.00. Assuming the original price is x, the original price would be:
18 = x × (1 + 20%)
18 = x × 1.20
18 = 1.20x
x = 18 / 1.20
x = $15.00
In conclusion, the original price was $15.00 but after the price increased by 20%, it went to $18.00.
