(a)
To find: The linear equation that gives the dollar value V of the game console in terms of the year t.
(a)

Answer to Problem 16CR
The equation for the dollar value V in terms of year t is
Explanation of Solution
Given data:
Dollar value of game console in 2018 is $299.
Decreasing rate per year is $59.80
Calculation:
The equation for the dollar value V in terms of year t:
As the rate is decreasing at $59.80 and dollar value at t=0 is $299
Conclusion:
The equation for the dollar value V in terms of year t is
(b)
To graph:
(b)

Explanation of Solution
Given data:
Dollar value of game console in 2018 is $299.
Decreasing rate per year is $59.80
Graph:
The graph of the equation is
Interpretation:
The graph is decreasing graph.
(c)
To find: Year in which game console have no values
(c)

Answer to Problem 16CR
The game console will have no values in 2023.
Explanation of Solution
Given data:
Dollar value of game console in 2018 is $299.
Decreasing rate per year is $59.80
Calculation:
The game console will have no values in 5 years which means in year 2018 + 5=2023.
Conclusion:
The game console will have no values in 5 years which means in year 2018 + 5=2023.
