Answer:
\(1.085x\)
Step-by-step explanation:
Let x represent original price of an item.
We have been given that sales tax is 8.5%. The cost of item after sales tax would be x plus 8.5% of x.
\(\text{Total price of item}=x+\frac{8.5}{100}\cdot x\)
\(\text{Total price of item}=x+0.085 x\)
\(\text{Total price of item}=1.085x\)
Therefore, our required expression would be \(1.085x\).
