Question

a sandwich shop purchases a used pizza oven for $725. after 5 years, the oven will have to be discarded and replaced. write a linear equation giving the value v of the equipment during the 5 years it will be in use. (use t to represent the year.)
v(t) =

Explanation:

Step1: Identify initial value

Initial value at $t=0$: $V(0) = 725$

Step2: Calculate annual depreciation

Annual depreciation: $\frac{725}{5} = 145$

Step3: Form linear equation

Linear depreciation model: $V(t) = \text{Initial value} - \text{Depreciation} \times t$
$V(t) = 725 - 145t$

Answer:

$V(t) = 725 - 145t$
