A truck is bought at the price of $67,000. The price decreases at the rate of .30 every year (t). Which equation matches this exponential model? Question 3 options:

A)

f(t) = 67(.70)t

B)

f(t) = 70(67,000)t

C)

f(t) = t(.70)67,000

D)

f(t) = 67,000(.70)t

f(t) = $67000(.30)^t          (Must use " ^ " to indicate exponentiation)

Step-by-step explanation:

This is an exponential function:

f(t) = $67000(.30)^t  (Must use " ^ " to indicate exponentiation)

the answer would be 484

step-by-step explanation:

just multiply 0.484 times 1,000 (formula)

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point
