Answer: $136.83
Step-by-step explanation:
Given : Sales tax rate = 6.9% =0.069
The list price of a pair of boots = $128
Then, the sales tax amount = Sales tax × List price
The sales tax amount[tex]= 0.069\times128=\$8.832[/tex]
Now, the total cost of the pair of boots = Sales tax amount +List price
= $8.832+128
=$136.832≈ $136.83 [Rounded to the nearest cent]
Hence, the total cost of the pair of boots = $136.83
