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

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.
