Mr. Scott plans a class trip for the 30 students in his class. He must pay the following costs per student:
• admission: $3.80
• bus: $10.40
• snack: $5.55
• supplies: $7.31
Round the costs to the nearest dollar and use them to estimate the total cost for the 30 students.
30$(3+10+6+7)
To estimate the total cost for the 30 students, we need to calculate the rounded costs for each expense per student and then multiply them by 30.
Let's start by rounding the costs per student to the nearest dollar:
• Admission: $3.80 rounds to $4
• Bus: $10.40 rounds to $10
• Snack: $5.55 rounds to $6
• Supplies: $7.31 rounds to $7
Now, let's calculate the total cost per student:
Total cost per student = Admission cost + Bus cost + Snack cost + Supplies cost
Total cost per student = $4 + $10 + $6 + $7
Total cost per student = $27
Finally, let's calculate the estimated total cost for the 30 students:
Estimated total cost for 30 students = Total cost per student x Number of students
Estimated total cost for 30 students = $27 x 30
Estimated total cost for 30 students = $810
Therefore, the estimated total cost for the 30 students is $810.
