Answer:

C. $18673.25

Step-by-step explanation:  

Let us find cost of item after 7.7% of sales tax. The price after 7.7% of sales tax will be 17250 plus 7.7% of 17250.

[tex]\text{The cost of item after sales tax}=17250+(\frac{7.7}{100}\times 17250)[/tex]

[tex]\text{The cost of item after sales tax}=17250+(0.077\times 17250)[/tex]

[tex]\text{The cost of item after sales tax}=17250+1328.25[/tex]

[tex]\text{The cost of item after sales tax}=18578.25[/tex]

Therefore, the cost of item after 7.7% of sales tax will be $18578.25.

To find the total cost of item let us add registration fee ($95) to $18578.25

[tex]\text{The total cost of item}=18578.25+95[/tex]  

[tex]\text{The total cost of item}=18673.25[/tex]

Therefore, the total cost of item is $18673.25 and option C is the correct choice.
