1. (4,1) is not a solution because when u sub it into the equation, it does not come out correct. It would be correct if it was (1,4).
2. C = 2.50d.....where C is the cost and d is the number of drinks bought. And if u pick any number for d, then u can solve for the cost (C).
14/420
14*3=42
14*0=0
Ur answer is 30
Prove
30*14=420
