A chemistry student was asked to make 100 L of 48% alcohol solution by mixing a 40% alcohol solution and a 60% alcohol solution. If x is the required amount (L) of the 40% solution and y is required amount (L) of the 60% solution, which of the following linear systems would best model this situation?

A) x + y = 100

40x + 60y = 48

B) x + y = 0.48

0.4 x + 0.6 y = 100

C) x+ y = 100

0.4 x + 0.6 y = 0.48

D) x + y = 100

0.4x + 0.6y = 0.48(100)

E) x + y = 100

0.4x + 0.6y = 0.48
