Step-by-step explanation:
so,
100% = $130
1 % = 100%/100 = 130/100 = $1.30
the price changed by 169 - 130 = $39.
how many % are that ?
as many % and times 1% fits into $39 :
39 / 1.3 = 30%
the price increase was 30%.

First you need to make a multiplier:
1-(12/100) = 0.78
Then you multiply the price by 1.12 to get the final answer;
22 * 0.78 = 17.16
This means it cost $17.16 after the 12% sales tax.
Hope this helps! :)
