Answer:
Total expenditure for the trip = $36.25
Explanation:
You are going to the movie with your younger brother and grandparents.
Senior citizens tickets cost $6 while your tickets cost $6.25 and your younger brothers ticket cost $4.25 .
Also there is an additional expenditure due to buying soda and popcorn and it costs $20.
Now we have to find the total cost for your trip to the movie theater.
For that we just need to add all the expenditures.Hence,
Total cost = 6 + 6.25 + 4.25 + 20 =$36.25
This is the total expenditure for the trip.
