question 1: you deposit $1200 at 6% compound interest annually. Find the balance in your account at the end of the given time period:
Compound Interest Formula::
A(t) = P(1+(r/n))^(nt)
a) 1 year
A(1) = 1200(1+0.06)^(1*1) = 1200*1.06 = $1272
----------------
b) 10 years
A(10) = 1200(1+0.06)^(1*10) = 1200*1.06^10 = $2149.02
---------------------------------------------------------------
question 2: a piece of machinery costs $240,000. Its value decreases at a rate of 12% per year. Write a model to represent the value of the machinery after an "x" amount of years.
A(x) = 240*0.88^x
