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.
