Answer:
Total cost of your trip would be $42.50
Explanation:
You are going to the movie theater with your grandparents and your younger brother.
Tickets cost for senior citizen = $6.00
so tickets costs for your grand parents = $6.00 × 2 = $12.00
Your ticket costs = $6.25
Your brother's ticket costs = $4.25
You spent an soda and popcorn = $20.00
Total cost = $12.00 + $6.25 +$4.25 + $20.00 = $42.50
The total cost of your trip to the movie theater would be $42.50.
