Answer:
81. $21.91
82. $35.84
Step-by-step explanation:
81. An online retailer ships one shipment of DVDs containing 8 DVDs. The cost of the shipment will be the price per DVD and the shipping cost together.
8 DVDs at 1.99 each is 8(1.99) = 15.92
Add the shipping cost 5.99 + 15.92 = 21.91
It costs all together $21.91
82. Repeat the same process above but for 15 dvds.
15 dvds cost 15(1.99) = 29.85
Add the shipping cost 5.99 + 29.85 = 35.84
