Answer: $3.51
Step-by-step explanation:
Given : Kevin buys 4 folding chairs.
Each chair costs $13.50.
The sales tax = 6.5% = 0.065
Cost of 4 folding chairs= 4 x Cost of one chair
[tex]=4\times13.50=\$54[/tex]
Amount of Sales tax = 0.065 x Cost of 4 chairs
= [tex]0.065\times54=\$3.51[/tex]
Hence, the amount of sales tax for Kevin's purchases = $3.51
