Janelle (age 12) and her cousin, marquita (age 14), go to 7 : 00 pm show. write an expression for the total cost of admission. what is the total cost?

The rates of admission to a movie show is $ 8 for an adult , children under the age 13  is $ 5 and the matinee ( before 6 pm ) is $ 3. In our case Janelle is a child since she is below the age of 13 and therefore will pay $ 5, while Marquita is an adult thus will pay $ 8. Therefore, $ 8 + $ 5 = $ 13
Therefore the total cost for the show will be $ 13
