ANSWER:

The system of equations that can be correctly used to find s, the cost in dollars of each standard photo and w, the cost in dollars of each wallet photo is: option A, since it easily allows to apply the method of matching by substitution and eliminate one variable and then substitute it into both original equations and find the other variable.
