Answer:
B. $14352.08
Step-by-step explanation:
Let us find cost of item after 7.2% of sales tax. The cost of item after 7.2% of sales tax will be equal to 15640 plus 7.2% of 15640.
[tex]\text{The cost of item after sales tax}=15640+(\frac{7.2}{100}\times 15640)[/tex]
[tex]\text{The cost of item after sales tax}=15640+(0.072\times 15640)[/tex]
[tex]\text{The cost of item after sales tax}=15640+1126.08[/tex]
[tex]\text{The cost of item after sales tax}=16766.08[/tex]
Therefore the cost of item after 7.2% of sales tax will be $16766.08.
Now let us add registration fee to the cost of item.
[tex]\text{The cost of item after registration fee}=16766.08+86[/tex]
[tex]\text{The cost of item after registration fee}=16852.08[/tex]
Now let us subtract $2500 trade allowance to find the total cost of the item.
[tex]\text{The total cost of item}=16852.08-2500[/tex]
[tex]\text{The total cost of item}=14352.08[/tex]
Therefore, the total cost of item will be $14352.08 and option B is the correct choice.
