Final answer:
To determine Teresa's bank account balance in 6 months, substitute 6 into the expression 1000+250x. The calculation reveals that she will have $2500 in her account after 6 months.
Step-by-step explanation:
The question asks us to calculate Teresa's bank account balance after 6 months, given the initial amount and the monthly deposit she makes. Using the expression 1000+250x, where $1000 is the initial amount and $250 is the amount deposited each month (with x representing the number of months), we can find the total amount after 6 months.
Substituting 6 for x, we have:
1000 + 250×6 = 1000 + 1500 = $2500
Therefore, Teresa will have $2500 in her bank account 6 months from now.
