Brain bought 2 shirts for 14.50 each and a pair of shoes for 29.99 the sales tax was 6%

Sedbober [7]

Cost of each shirt bought by Brain = 14.50
Then
Cost of 2 shirts bought by Brain = 2 * 14.50
      = 29
Cost of a pair of shoes = 29.99
Total amount spent by Brain before tax = 29 + 29.99
   = 58.99
Percentage of sales tax that needs to be paid = 6%
Amount of sales tax that needs to be [paid = (6/100) * 58.99
   = 353.94/100
   = 3.54
So
the total amount spent by Brain including tax = 58.99 + 3.54
   = 62.53
I hope this is the answer you were looking for.
