Question

A plane ticket costs c dollars for an adult and k dollars for a child. Find an expression that represents the total cost for 8 adults and 7 children.

Answer 1

Sure, we can start by calculating the total cost for the adults. We know that there are 8 adults, and each adult will cost c dollars. Therefore, by multiplying the cost per adult (c) by the number of adults (8), we can find the total cost for the adults.

Now, let's consider the children. Each child's ticket costs k dollars and there are 7 children. Therefore, the total cost for the children will be found by multiplying the cost per child's ticket (k) by the number of children (7).

So our total cost for all the plane tickets will be found by adding together the total cost for the adults and the total cost for the children.

Here's how it looks:

1. Calculate the total cost for the adults:
8 adults * c dollars/adult = 8c total dollars

2. Calculate the total cost for the children:
7 children * k dollars/child = 7k total dollars

3. Add the total cost for adults to the total cost for the children to get the total cost for all:
8c total dollars + 7k total dollars = 8c + 7k total dollars.

So, that's the total cost for 8 adults and 7 children.

Answer 2

Answer: To find the total cost for 8 adults and 7 children, we can use the given information that a plane ticket costs c dollars for an adult and k dollars for a child.

1. Multiply the cost of an adult ticket, c, by the number of adults, 8. This will give us the total cost for the adults.

Total cost for adults = 8c

2. Multiply the cost of a child ticket, k, by the number of children, 7. This will give us the total cost for the children.

Total cost for children = 7k

3. Add the total cost for adults and the total cost for children to get the total cost for both adults and children.

Total cost = Total cost for adults + Total cost for children

Total cost = 8c + 7k

Therefore, the expression that represents the total cost for 8 adults and 7 children is 8c + 7k.
