Answer:
$19.80
Explanation:
Provided that the ticket for children costs $4.30 and the ticket for adults costs $6.50, it is easy to get the total cost by multiplying the cost of each ticket to the number of tickets and adding the products.
Adult's Ticket Cost
2 adults x $6.50 = $13
Mrs. Brown has to pay $13 for two adult tickets.
Children's Ticket Cost
4 children x $4.30 = $17.2
Mrs. Brown has to pay $17.2 for four children tickets.
Let's add both adult's ticket cost and children's ticket cost to get the total cost of the tickets.
$13 + $17.2 = $30.2
The total cost of the tickets is $30.2.
Let's subtract the total cost from the $50 bill paid by Mrs. Brown.
$50 - $30.2 = $19.8
Mrs. Brown received $19.80 as change.
