Answer:
(a) $ 1.60
(b) $ 0.96
Step-by-step explanation:
(a) Cost of printing 2000 posters = Cost of first thousand + cost of second thousand = 1500 + 1200 = 2700
Total cost = 2700 + 500 = 3200
Average Total Cost = Total cost/Number of posters = 3200/2000 = $ 1.60
(b) Cost of printing 10000 posters = Cost of first thousand + cost of second thousand + (800 Ă Number of additional thousands)
Number of additional thousands = (10000 - 1000 - 1000)/1000 = 8000/1000 = 8
Cost of printing 2000 posters = 1500 + 1200 + (800 Ă 8) = 2700 + 6400 = 9100
Total cost = 9100 + 500 = 9600
Average Total Cost = Total cost/Number of posters = 9600/10000 = $ 0.96
