Exercise 45

Referring back to Exercise 26, you have just been hired as the buyer for the kitchen division of Shopper's Mart, a general merchandise retailer. After looking over the discounts offered to the previous buyer by the vendor, you decide to ask for better discounts.
After negotiating with the vendor's salesperson, you now can buy blenders at trade discounts of 20/20/15 and juicers at 25/15/10. In addition, the vendor has increased the volume discount to 61 2%.
a. How much would have been saved with your new discounts based on the quantities of the previous order (Exercise 26)?
b. As a result of your negotiations, the vendor has offered an additional discount of 2% of the total amount due if the invoice is paid within 15 days instead of the usual 30 days. What would be the amount of this discount?
