21. The correct answer is (C). Statement (1) alone essentially provides one linear

equation in two variables: 0.75M

1.25S. In this equation, you cannot solve for either

M or S. An infinite number of value pairs are possible. Statement (2) alone presents a

similar situation: one equation in two variables (M

S). Together, however,

the two statements provide a system of two distinct equations in two variables, which

you can solve. Although there’s no need to find the solution, one way to do so is to simply

substitute (M

1000) for S in the equation derived from statement (1), then solve for M
