The fax mailer bought a fax machine for $600. The fax machine depreciates at a rate of $20 a month. Find a function that can be used to determine the value of the fax machine t months after purchase.
Complete the model below
F(t)=__?
F(t) = 600 - 20 t
for t </= 30
To determine the value of the fax machine t months after purchase, we can subtract the depreciation from the original purchase price.
The fax machine depreciates at a rate of $20 per month. This means that every month, the value of the fax machine decreases by $20.
Therefore, the function that can be used to determine the value of the fax machine t months after purchase (F(t)) is:
F(t) = $600 - ($20 × t)
Here, F(t) represents the value of the fax machine t months after purchase, $600 is the original purchase price, $20 is the rate of depreciation per month, and t is the number of months after purchase.
