um I need much assistance with my homework in math class as soon as possible please because I have been stuck for many hours

Question

1.) The value of a car bought new for $28900 decreases 15% each year. Identify the function for the value of the car. Does the function represent growth or decay?

A.) V(t) = 28900(0.15)t; decay

B.) V(t) = 28900(0.85)t; decay

C.) V(t) = 28900(0.85)t; growth

D.) V(t) = 28900(0.15)t; growth

 

 

2.) The value of a treadmill bought new for $1000 decreases 5% each year. Use a graph to predict the value of the treadmill in 5 years.

A.) ≈ $902.50

B.) ≈ $773.78

C.) ≈ $814.50

D.) ≈ $857.38

Answer 1

1.) A(t) = 28900(0.85)^t; decay because base b= 0.85 < 1

2.) A(t) = 1000(0.95)^t; A(5) = 1000(0.95)⁵ = $

Answer is 773.78 is B.)

Answer 2

1) V(t) = 28900(1 - 0.15)^t What does "decreases" mean

2) Did you draw the graph?
