Hi

Problem looks quite staright forward. You need values of two variables t and s to solve this problem and therefore C is correct.

Thanks,
sm

B
The question actually asks for total cost
r(100)+s(50)= ?. So, We need the value for r and s to get the final answer.

1. says about s, which is 4 still we don't know the value of r.
2. 2r + s = 10. If you look at the question we framed and this equation. The are proportionate. Just multiply this equation by 50, you will get the answer.
