Final answer:
The cost for 1 ticket to the local aquarium is $40 and the cost for 5 tickets is $100.
Step-by-step explanation:
To calculate the cost for 1 ticket to the local aquarium, we need to consider the fixed costs and the variable costs. The fixed cost of production is $20. The total variable cost for one ticket is also $20. Therefore, the total cost for 1 ticket is $20 (fixed cost) + $20 (variable cost) = $40.
To calculate the cost for 5 tickets, we need to find the total variable cost for 5 units. From the given information, the total variable cost for five tickets is $80. Therefore, the total cost for 5 tickets is $20 (fixed cost) + $80 (variable cost) = $100.
