4.35-.50= 3.85 divide that by 3= 1.28$ per game
Speed of the boat = u
speed of the current = v
in downstream,
u - v = 105/5
u - v = 21
in upstream
u + v = 105/7
u + v = 15
add both equations
2u = 36
u = 18
v = -3
so
speed of the boat = 18 km/h
speed of the current = 3 km/h

I agree with the answer being B because since it's a common ratio you could just multiply -1/4 with -2 and keep doing that with each new term
