A $450 smartphone depreciates 12% each year. Which of the following models the value of the phone after t years?
A = .88 t + 450
A = 450 ( 0.88 ) t
A = − 0.12 t + 450
TA = 450 ( 0.12 ) t
A = 450 ( 0.12 ) ( t )
Compute the absolute and relative change for the values below. Use the table to select the appropriate model for the data below.
| Time | Value | Absolute Change | Relative Change |
| 0 | 138.500 | ||
| 1 | 155.76 | ||
| 2 | 173.02 | ||
| 3 | 190.28 |
17.26 ( 1.385 ) t
138.5x + 17.26
138.5(x+17.26)
138.5 ( 18.26 ) t
17.26x + 138.5
138.5 ( 17.26 ) t
