A plane ticket costs c dollars for an adult and p dollars for a child. Find an expression that represents the total cost for 3 adults and 6 children.
3c+6p
To find the total cost for 3 adults and 6 children, we need to multiply the cost of 1 adult ticket with 3 (since there are 3 adults) and the cost of 1 child ticket with 6 (since there are 6 children).
The expression that represents the total cost is:
3c + 6p
To find the total cost for 3 adults and 6 children, we need to multiply the cost per adult by 3 and the cost per child by 6, and then add the two results together.
Let's call the cost per adult "c" and the cost per child "p".
The total cost for 3 adults would be 3 times the cost per adult, which is 3c.
The total cost for 6 children would be 6 times the cost per child, which is 6p.
Therefore, the expression that represents the total cost for 3 adults and 6 children is 3c + 6p.
