Suppose you had a balance of [tex]$2915 in your checking account and wrote checks for $[/tex]90, [tex]$282, $[/tex]402, and $521.

Estimate the four check amounts and the beginning balance to the nearest hundred to estimate the new balance.



Answer :

Let's estimate the initial balance and the amounts of the four checks to the nearest hundred and then calculate the estimated new balance.

Step 1: Estimate the initial balance to the nearest hundred

1. The initial balance is [tex]$2915. - Rounding $[/tex]2915 to the nearest hundred gives us [tex]$2900. Step 2: Estimate each check amount to the nearest hundred 1. Check for $[/tex]90:
- Rounding [tex]$90 to the nearest hundred gives us $[/tex]100.

2. Check for [tex]$282: - Rounding $[/tex]282 to the nearest hundred gives us [tex]$300. 3. Check for $[/tex]402:
- Rounding [tex]$402 to the nearest hundred gives us $[/tex]400.

4. Check for [tex]$521: - Rounding $[/tex]521 to the nearest hundred gives us [tex]$500. Step 3: Calculate the total rounded check amount 1. Adding the rounded amounts for each check: - $[/tex]100 (check 1)
- + [tex]$300 (check 2) - + $[/tex]400 (check 3)
- + [tex]$500 (check 4) - Total: $[/tex]1300.

Step 4: Estimate the new balance

1. Subtract the total estimated check amount from the estimated initial balance:
- [tex]$2900 (estimated initial balance) - - $[/tex]1300 (total estimated check amount)
- Equals: [tex]$1600. So, the estimated new balance after writing the checks, rounded to the nearest hundred, would be $[/tex]1600.
