Question 1191582
i believe what you are saying is:


if a piece of equipment originally cost c dollars, then the cost of simillar equipment that is x times as large will be approximately x * .6c dollars.


your example states that, if the original equipment cost c dollars, then new equipment with twic3e the capacity of the old equipment would cost 2 * .6 * c dollars = 1.516 * c dollars.


unfortunately, as far as i can tell, 2 * .6 * c dollars is equal to 1.2 * c dollars.


i don't know where 1.516 * c dollars came from.
it is very confusing to me, unless i am able to understand how you arrived at that figure.


if i assume the formula is as you stated, then i would go with 2 * .6 * c 1.2 * c.


if a new equipment is 4 times as large, then the rule of point six would state that the cost of the equipment would be equal to 4 * .6 * c = 2.4 * c dollars.


let me know if you have any questions and how you obtained 1.516 rather than 1.2  when the new equipment was 2 times as large.
