Some of the students from Millennium Middle School are taking a trip to a museum. In all fewer than 60 students will go on the trip. The cost for food and admission to the museum is $18 per student. The students will travel on one bus to the museum. The cost of the bus is $800. Complete the table below to show the total cost for food, admission, and the bus for different numbers of students to the museum.

Answer 1

Number of students Total cost

0 $800

20 $1160

30 $1340

40 $1520

50 $1700

Step-by-step explanation

Given

Cost per student = $18

The cost of the bus = $800

Step-by-step solution:

The total cost for food, admission, and the bus can be calculated using;

18a + b

Where a is the number of students and b is the cost of the bus.

For 30 students:

$18(30) + $800 = $540 + $800 = $1340

For 40 students:

$18(40) + $800 = $720 + $800 = $1520

For 50 students:

$18(50) + $800 = $900 + $800 = $1700
