Hey there!
To start, since you already know your total without the tax, 60 dollars, now you have to find the sales tax.
Since the sales tax is 5% of the total, multiply 5% to 60. To do this, first convert 5% to a decimal by moving the decimal left two times. This would be 0.05. Now, multiply your 0.05 to 60:
0.05*60=3
Finally, add this sales tax to your total:
60+3=63
Therefore, your final total is 63 dollars.
