Step-by-step explanation:
Given:
Total number of students went to winter festival = 68
In Group A:
Number of students = 23
Cost for polar express ride = $6.75
We need to find the cost of group A amusement ride.
Cost of group A amusement ride can be calculated by multiplying Number of students and Cost for polar express ride
Cost of group A amusement ride = Cost for polar express ride × Number of students = 23 × $6.75 = $155.25
Hence Cost of Group A amusement ride is $155.25.
In Group B:
Number of students = 25
Cost for Rudolph's reindeer ride = $4.50
We need to find the cost of group B amusement ride.
Cost of group B amusement ride can be calculated by multiplying Number of students and Cost for Rudolph's reindeer ride
Cost of group B amusement ride = Cost for Rudolph's reindeer ride × Number of students = 25 × $4.50 = $112.5
Hence Cost of Group B amusement ride is $112.5.
In Group C:
Number of students = 20
Cost for Rudolph's reindeer ride = $4.50
Cost for polar express ride = $6.75
We need to find the cost of group C amusement ride.
Cost of group C amusement ride can be calculated by multiplying Number of students and Cost for Rudolph's reindeer ride and then add Number of students multiplied Cost for polar express ride
Cost of group C amusement ride = Cost for Rudolph's reindeer ride × Number of students + Cost for polar express ride × Number of students= 20 × $4.50 + 20 × $6.75 = $90 + $135 = $225
Hence Cost of Group C amusement ride is $225.
Final Answer.
Cost of Group A amusement ride is $155.25.
Cost of Group B amusement ride is $112.5.
