Question

On a trip, the fare was 50¢ for each adult and 25¢ for each child. If 30 passengers paid $12.25, how many adults and children went?
Is this the right way to set up the equation?
50x + 25(30 - x) = 1225

Answer 1

it is, yes..

Answer 2

D+C=30
C= 30-D
12.25=.5D+.25C

12.25=.5D+.25(30-D)

Answer 3

I'm not sure lol

Answer 4

Not quite.... 25x + 50x = 30(1225) is the answer.
