The total 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 that the one-time cost to be able to make cards is $100, 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?

Answer 1

Let's start by figuring out the repeated cost per card:

- To make 500 cards, the repeated cost is $1,100 - $100 = $1,000. So the cost per card is $1,000 / 500 = $2.
- To make 650 cards, the repeated cost is $1,400 - $100 = $1,300. So the cost per card is $1,300 / 650 = $2.

Now we have enough information to estimate the total cost for 1,000 cards:

- To make 1,000 cards, the one-time cost is still $100.
- The repeated cost per card is $2, so the total repeated cost is $2 * 1,000 = $2,000.
- Therefore, the total cost for 1,000 cards is $100 + $2,000 = $2,100.
