Question

At the carnival a Ferris wheel ride costs two tickets and a roller coaster ride costs 4 tickets. Miles has 16 tickets. Write the linear equation for the number of rides he can ride.

Answer 1

f = number of Ferris wheel rides at 2 tickets each

r = number of roller coaster rides at 4 tickets each

2f + 4r = 16,

where f and r are integers.
