Question

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 300 cards is $900.00, and the total cost to make 650 cards is $1,600.00. What is the total cost to make 1,000 cards? Round your answer to the nearest dolla

Answer 1

The cost to make 1000 cards would be $2,300.

To answer this question, we must find the linear equation that models this situation above.

Start with our two points:
(300, 900)
(650, 1600)

If you find the slope, you will have 700/350 or 2. Then, you can find the y-intercept of 300.

Your equation will be: y = 2x + 300
Just input 1000 for x and you will have an output value of $2300.
