college algebra word problem

Question

If the total amount of money you had to invest was $8,000 and you deposit x amount in one investment, how can you represent the remaining amount in dollars?

Answer 1

Hello, thank you for taking the time to post your question!

What it’s getting at here is that after you invest the “x” amount of money, you would still have (8000 – x) leftover to invest.

So you can represent the remaining amount as $8,000 – x

I hope that helps you get moving in a better direction on this type of question! Feel free to reach out if you have any additional questions beyond that :)

Answer 2

x is one investment

$8,000 is the total to be invested

the difference, the remaining amount in dollars is: $8,000 - x

the investment plus the remainder sum to 8000

x + (8000-x) = 8000
