Solution
The correct option is A$2500 To round off a number to the nearest hundred, we have to observe number at tens place.
For the price of computer we have $1627 where 2<5 so we round it down to 1600.
And for the phone we have $892 where 9>5 thus rounding it up to 900.
So the total expenditure of Bip would be $1600+$900=$2500
This is very close to the exact expenditure which is $1627+$892=$2519
