Mr. Burn's class is taking a field trip to the planetarium. The trip will cost $27 for each student. There are 18 students in his class.
Part A: Round each factor to estimate the total cost of the field trip.
To estimate the total cost of the field trip, round each factor:
The cost per student is $27.
There are 18 students in the class.
Rounded:
The cost per student is approximately $30.
The number of students is approximately 20.
Part A: Estimate the total cost of the field trip.
Multiply the rounded factors:
$30 (estimated cost per student) × 20 (estimated number of students) = $600 (estimated total cost of the field trip)
To estimate the total cost of the field trip, we need to round the number of students in the class and the cost per student.
- The number of students is 18. We can round it to the nearest ten, which would be 20.
- The cost per student is $27. We can round it to the nearest ten, which would be $30.
So the rounded estimate for the total cost of the field trip would be 20 students * $30 per student = $600.
