let's say an item cost x amount. for each item you buy, beyond the first, cost increases by x / 10. the item provides a unit of concern.
so, the problem is that i need to create a chart with the trends, but need to start with the equations.
to use an example (using obviously made up, easy numbers):
a small airplane initially costs $5, and provides a speed of 3. (assuming the factor of increase per plane is taking into account the cost of the space of storage) the second plane would cost $5.50, and provides an additional 3 of speed.
medium plane initially costs $10, with speed of 6. second would cost $11, providing additional 6 speed.
question/concern:
i need to find out a way to see the trends across the next 100 purchases, based on the costs per unit of speed. meaning, first plane costs ($5/3 speed) ~ $1.67. second, ($5.50/6) ~$0.92, and so on.
this applying to each level (small plane, medium plane, large...). then, the graph must show each, small plane's relative amount as one line, medium as another, etc.
------------------------------------------------
maybe this would work?
initial cost of unit = x; number of units have = n; unit of speed = s
[=(x/10s) + (x/sn)] {derived from: ((x/10)*n + x)/sn)} lol racking my brain here....
