Question 1140466: The value of a machine, V, at the end of t years is given by V=C(1−r)t, where C is the original cost and r is the rate of depreciation. Find the value of a machine at the end of 2 years if the original cost was $795 and r=0.3. Round to the nearest cent.

You can put this solution on YOUR website!
v = c * (1 - r) ^ t

c = 795
r = .3

formula becomes v = 795 * (1 - .3) ^ 2

solve for v to get v = 389.55

that's your solution.
