The sale tax of 1 chair is = 13.50 x 6.5/100 = 0.8775
The sale tax of 4 chairs is = 0.8875 x 4 = 3.51

First, find the total cost of the folding chairs by multiplying $13.50 and the number of folding chairs (4). Next, convert 6.5% to a decimal, which is 0.065, and multiply that sales tax with the total cost of 4 folding chairs, which you found out is $54. 

Your final answer is $3.51 for the sales tax.
