Hey there!
To start, first find out the amount of money you have tipped. To find this, multiply your amount of money spent by the percent you tipped:
80*22%
=80*0.22
=17.6
Now, add the amount of tipped money to your amount spent:
80+17.6
=97.6
Now, because you always add on the taxes last, multiply your amount spent (with the additional tip) with the percent of tax:
97.6*6.7
=97.6*0.067
=6.5392
Finally, add this tax amount to 97.6 and round your total to the nearest cent (the hundredths place):
97.6+6.5392
=104.1392≈104.14
Therefore, your total amount of money spent would be $104.14.
Hope this helps and have a marvelous day! :)
