HELP!
The Richards family (2 adults and 2 children, ages 6 and 8) are taking a bus as transportation between Harrisburg, PA and Pittsburgh, PA. The fare is $16.80 for a one-way ticket. Children ride for 1/2 price. A round trip fare is double the one-way fare. If the Richards travel round trip, what is the total cost for the whole family? _

Respuesta :

Adults pay = $33.60
Children pay = $16.80 (it's half price but if they take a round trip it's double the price. Therefore it's $16.80) then multiply both by two and add them together.

2 ($33.60+$16.80) = $100.80
