Answer:
Answer is 500
btw did round sorry
Step-by-step explanation:
First year
4,000 divided by 2,000=2,000
Second year
2,000 divided by 2=1,000
Third year
1,000 divided by 2=500
Yes it is a rational number
I would multiply both sides by negative one and then take the smaller of the two variables and subtract that from both sides, simplify and solve.
