The final price inculding tax after discount is $ 47 and expression used is:
Required expression = price of item - discount price + tax on item
<h3><u>Solution:</u></h3>Given that 40% discount on an item costing $74 plus 7% tax
So cost of item = $ 74

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

Price including tax = 44 + 7 % of 44
Price including tax =
Thus the final price inculding tax after discount is $ 47
