The final price inculding tax after discount is $ 47 and expression used is:
Required expression = price of item - discount price + tax on item
Solution:
Given that 40% discount on an item costing $74 plus 7% tax
So cost of item = $ 74
Tax = 7 %
Discount = 40 %
The expression which can be used to find price after discount including tax is:
Required expression = price of item - discount price + tax on item
Let us first find the price after discount
Price after discount = cost of item - 40 % of cost of item
Price after discount = 74 - 40 % of 74
[tex]= 74 - \frac{40}{100} \times 74\\\\= 74 - 29.6 = 44.4[/tex]
Thus the price after discount is approximately $ 44
Now tax is 7 % which means 7 % of $ 44
Price including tax = 44 + 7 % of 44
Price including tax = [tex]44 + \frac{7}{100} \times 44 = 44 + 3.08 = 47.08[/tex]
Thus the final price inculding tax after discount is $ 47
