x = items bought
k = koeficient (or cost of 1 item)
y = cost
Here is the problem..
Robinson Wholesale Company paid $1340 for 500 items. Later they bought 800 items for $1760. Assume that the cost is a linear cost function of the number of items.
Write the equation..
Thank you for any help you may provide! I am clueless with this stuff!!
