Thread: Finite Math help please and thank you..

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!!

John

x = items bought
k = koeficient (or cost of 1 item)
y = cost

this paints a very clear picture for me. ty!!
