The cost of a machine is supposed to depreciate each year by 12% of its value at
the beginning of the year. If the machine is
valued at 344,000 at the beginning of 2008,
find its value
(i) at the end of 2009.
(ii) at the beginning of 2007.​

i) 302720

ii) 390909.09

Step-by-step explanation:

So to that end, here's the formula:

In part i, we do the following:

In part ii, we do the following:

what is the answer?

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
