The New Balance is _____?

Answer 1

Answer:

The balance is $18.

Step-by-step explanation:

You are in the negatives so you want to add so that your balance is positive.

1. -20 + 38 = x

x will be the variable that will be the final balance.

2.  18 = x

If you put this on a number line, you will see that when you add 38 to -20, your balance becomes 18. Therefore, your answer is 18.
