Dainel paid $22 for a water bottle. this amount includes 5% tax. what was the cost of the item befor tax?

20.90 would be the item before tax. To get the amount of tax, I multiplied 20 by 0.05 and subtracted that amount from 22

So $22 is after the 5% tax. Just enter 22 / 1.05 (which is 20.95) roundest to the nearest hundredth. Round it however you are supposed to for this question, but given that the final price is $22 (with 5% tax), you just need to divide it by 1.05 (non-tax price + 5% of it). Hope this helps!

If you round to the nearest hundredth, the answer is $20.95.

The answer is 10. sorry i was wrong the 1st time
