Answer:
Considerations:
Also,
A positive number divided by a positive number results in a positive quotient, and its opposite is always negative.
The fraction 
can be described as a positive number divided by a negative number, which always result in a negative quotient.
The fractions have same value, so Liam is correct.
A. f(t)=9000-1000t; Since 9000 is the number we start on, that is written as the constant. And since the value decreases by $1000 each year, we can put the $9000 it costs currently and will decrease by $1000 per year (t), this can be written as the function f(t)=9000-1000t
B. $6000; Just plug 3 into the equation to find the answer.
f(t)=9000-1000(3)
f(t)=9000-3000
f(t)= 6000
It costs $6000 after three years
C. $3500; To solve this just subtract 500 from 9000 to get 8500, and plug this in as the constant in our function.
f(t)=8500-1000(5)
f(t)=8500-5000
f(t)=3500
The answer is $3500
