2.99

The way to get the answer is as follows. Write down the number. Now write 0.0050 below it. The rationale is as follows. It is the hundredth place you want the number rounded to, so you write a 5 below the thousandths position and zero everywhere else as shwon below and add the numbers. From the result truncate everything after the hundredths poistion giving you 2.99 as the answer.
