Answer:
The expression representing the Total Cost of the item is [tex]P + 0.07P[/tex].
Step-by-step 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 = [tex]\frac{7}{100}\times P = 0.07P[/tex]
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 = [tex]P + 0.07P[/tex]
Hence The expression representing the Total Cost of the item is [tex]P + 0.07P[/tex].
