Question

Chris purchased a tablet for $650. The tablet depreciates at a rate of $25 per month.

Write and simplify an equation that models the value V(m) of the tablet after m months.

Answer 1

Let d equal the final amount it depreciates.

Let m equal the number of months.

Since d is the final amount, we put this at the very end of the equation.

Since it depreciates $25 every month, this number is going to be subtracted from the total price of the tablet ($650).

The final equation comes out too: d = 650 - 25m

Best of Luck!
