How do I figure this out?
The fax mailer brought a fax mcahine for $600. The fax machine depreciates at a rate of $20 a month.
(a) find a function F that can be used to determine the value of the fax machine t months after purchase
complete the model below:
f (t) = ?
What you don't know is the # of months, so t would represent that number. If you lost $20/month, you would show this by multiplying 20 and t. Since the total price is $600, you would subtract what you were losing from the $600 to get your answer. Hope this helps :-).
To determine the value of the fax machine t months after purchase, you need to use the given information that the fax machine depreciates at a rate of $20 per month.
The initial cost of the fax machine is $600, and it depreciates by $20 every month. This means that after t months, the value of the fax machine would be $600 minus $20 multiplied by t.
So, the function F that can be used to determine the value of the fax machine t months after purchase is:
f(t) = 600 - 20t
By substituting the value of t into the function, you can calculate the value of the fax machine at any given time after the purchase.
