Question

i don't really understand this question?

Write a paragraph explaining how you would prepare financially for this trip. Would you invest the $1500 and wait until it grows to $2000? Would you add to the investment of $1500 so it will grow to $2000 by the time you want to take the trip? Would you invest the $1500 and come up with the rest of the money when you want to take the trip? Explain your answer.
