Answer 1

The expression representing the Total Cost of the item is

Explanation:

Given:

Price of Certain item = 'P' dollars

Sales tax =7%

We need to find the expression for Total Cost of the item when tax is applied.

we will first find the Amount deducted in tax;

Amount deducted in Tax is equal to Percentage of sales tax multiplied by Price of Certain item and then divide by 100

Framing in equation form we get;

Amount Deducted in Tax =
`(7)/(100)* P = 0.07P`

Now Total Cost of the item is equal to sum of Price of Certain item and Amount deducted in tax.

Expressing in expression form we get;

Total Cost of item =
`P + 0.07P`

Hence The expression representing the Total Cost of the item is
`P + 0.07P`.
