Answer :
Final answer:
To round to the nearest hundred, you look at the tens digit of the amount. For an account balance of 631 pounds, you round down to 600 pounds. For a negative balance like negative 117 pounds, after rounding the absolute value to 100 pounds, you reapply the negative sign to get negative 100 pounds.
Explanation:
The question asks us to round the amount of money in somebody's bank account to the nearest hundred. Rounding to the nearest hundred involves looking at the tens digit and determining whether it is 5 or above, in which case you round up, or 4 or below, in which case you round down. If someone has 631 pounds in their account, the tens digit is a 3, so you would round down to 600 pounds. If the principal amount is negative, as in the case of Jordan's account which is negative 117 pounds, we still look at the tens digit. The tens digit for Jordan is 1, so we would round up the absolute value to the nearest hundred (100) and then apply the negative sign, resulting in negative 100 pounds.
