Final answer:
To find the total cost for 12 adult tickets and 18 kids tickets at the Natural History Museum, multiply the cost of each ticket type by the number of tickets and add the results together. The total cost for a variable number of adult tickets and k kids tickets can be calculated using the formula a × $10 + k × $6.
Step-by-step explanation:
To find the total cost for 12 adult tickets and 18 kids tickets at the Natural History Museum, we need to multiply the cost of each type of ticket by the number of tickets. For adults, the cost is $10 per ticket, so for 12 adult tickets it would be 12 × $10 = $120. For kids, the cost is $6 per ticket, so for 18 kids tickets it would be 18 × $6 = $108.
Therefore, the total cost would be $120 + $108 = $228.
If we want to find the total cost for a number of adult tickets (a) and k kids tickets, we need to know the value of a and k. Since the question doesn't specify these values, we can't provide a specific total cost.
However, we can use the given information to calculate the cost formulaically. The total cost in this case would be a × $10 + k × $6.
For example, if you have 5 adult tickets and 10 kid tickets, the total cost would be:
Total cost = ($10 × 5) + ($6 × 10)
Total cost = $50 + $60
Total cost = $110
