A company buys a machine for $225,000 that depreciates at a rate of 30% per year. Find a formula for the value of the machine after n years. V(n) =

Step-by-step explanation:

In this problem we are expected to model the depreciated value of the machine after some years of purchase (n years)

initial value of the machine is $225,000

after a year it reduces by 30%

Therefore the new value is now 70% of the initial value

= $157,500

After another year it reduces by 30%

Hence the new value is

= $110250

that after n years the value will be

step-by-step explanation:

*calories burned = (weight)(calorie factor)*

calories burned = 180 (0.65)

calories burned = 117

the calories he used up is 117, which is 65% of his weight.
