Averages and Rounding
1. B: When rounding the decimal to the nearest tens place, look to the digit that is one place to the
right, or the ones place. Since the digit in the ones place is greater than 5, the number will be
rounded up to the next 10, giving a rounded number of 910.
2. C: The weighted average may be written as (3.89)+(3.92)+(2.94)+(2.81)+(1.85)/11, which is
approximately 88.9.
3. D: The average daily cost may be written as 5.43+5.43+3.54+3.54+7.89/5, which equals 5.17. The
average daily cost was $5.17.
4. C: When rounding the decimal to the nearest hundredths place, look to the digit that is one place
to the right, or the thousandths place. Since the digit in the thousandths place is less than 5, the digit
in the hundredths place will remain. Thus, the rounded number is 1230.93.
