writing your data as ordered pairs, I would get:
(500,1100) and (650,1400)
slope or (change in cost)/(change in number) = (1400-1100)/(650-500)
= 300/150
= 2
so if x is the number of cards and y is the total cost
y = 2x + b
plug in (500,1100)
1100 = 2(500) + b
b = 100
y = 2x + 100 or cost = 2(number of cards) + 100
so if number of cards = 1000, cost = ....
The cost for a business to make greeting cards can be divided into one-time costs (e.g., a printing machine) and repeated costs (e.g., ink and paper). Suppose the total cost to make 500 cards is $1,100, and the total cost to make 650 cards is $1,400. What is the total cost to make 1,000 cards? Round your answer to the nearest dollar.
A. $2,000
B. $2,100
C. $2,250
D. $2,300
