Product #1: iTech Device The current resale value is $300. The resale value is expected to decrease by 30% per year for the next several years. Product #2: Dynasystems Device The current resale value is $300. The resale value is expected to decrease $45 per year for the next several years. Define formulas to model the expected resale value, V, in dollars for each device as functions of the number of years from now, x.

Net resale value after x years for product #1 is $300 - $90x

Net resale value after x years for product #2 is $300 - $45x

Step-by-step explanation:

Resale value of product 1 = $300

Decrease in resale value = 30% per year

Thus,

Net resale value after x years will be = Initial Resale value - x (30% of $300)

or

= $300 - x (0.3 * $300)

= $300 - $90x

Hence,

Net resale value after x years for product #1 is $300 - $90x

Resale value of product 2 = $300

Decrease in resale value = $45 per year

Thus,

Net resale value after x years will be = Initial Resale value - $45x

or

= $300 - $45x

Hence,

Net resale value after x years for product #2 is $300 - $45x
