A student prepared the following spreadsheet model to calculate the final price of clothing items which are sold at a discount. To be complete, the student included a calculation of sales tax in the final price, given the original price (180), discount (0.2), and sales tax rate (0.09) shown below. A B 1 2 Original Price 180 3 Discount(%) 0.2 4 Discount ($) = B2 × B3 5 Net Price = B2 − B4 6 Sales Tax(%) 0.09 7 Sales Tax($) = ROUND(B5 × B6,2) 8 Final Price = ROUND(B5 + B7,2) Determine what values the spreadsheet should display.
