13 / 8.45 will give you cost per
cost per copy* Then multiply that by 27.
Let y = cost, x = # copies you can use the model y = k*x
The answer is 41.53? @iGreen
@perl
I get that too..but it doesn't seem right. What do you think? @perl
Lol, nevermind.
It doesn't look right to me neither.
lets do it this way
13 doubled is 26..which is close to 27. 8.45 * 2 = 16.9 So the cost of 26 copies is 16.9..27 should just be a little more, right?
it costs $8.45 / 13 per copy or $0.65 per copy. Now multiply that by the number of copies
Ohh! That sounds right..we divided the wrong way..lol.
right :)
Wait what...
the cost per copy should have been $8.45 / 13
The equation we are using is ( cost per copy ) * # copies = total cost
So 17.55? @perl
yes
