• The postal service of St. Vincent, an island in the West Indies, recently introduced a limited edition deluxe souvenir sheet priced at $15.00 each. The initial market response was quite positive, with an increase in unit sales compared to the regular souvenir sheets. The postal service sold a total of 50,000 units of the deluxe souvenir sheet. Based on the given information, calculate the following: What was the postal service's increase (decrease) in total contribution margin when it sold 50,000 deluxe souvenir sheets at $15.00 each, compared to selling 80,000 regular souvenir sheets at $8.00 each? By what percentage did the St. Vincent post office increase the selling price for the deluxe souvenir sheet compared to the regular souvenir sheets? Additionally, calculate the percentage increase in unit sales for the deluxe souvenir sheet compared to the regular souvenir sheets. (Round your answers to one-tenth of a percent.) If the postal service wants to maintain the same total contribution margin per unit for the deluxe souvenir sheets as it did for the regular souvenir sheets, what selling price should they set for the deluxe souvenir sheet?

Calculate the number of deluxe souvenir sheets the postal service would need to sell at the price determined in question 3 to equal the total contribution margin earned by selling 80,000 regular souvenir sheets at $8.00 each. (Round your answer to the nearest whole number.
