Write a system of equations to describe the problem situation. It is not necessary to solve the problem. Nancy has $3.50. She has only dimes (x) and quarters (y). She has 30 coins altogether.
A) x = 30 - y, 0.10x + 0.25y = 3.50
B) x - y = 30, 0.10x + 0.25y = 3.50
C) y - x = 30, 0.10x + 0.25y = 3.50
D) x + y = 30, 0.05x + 0.25y = 3.50
E) x + y = 30, 0.05y + 0.25x = 3.50
A) x = 30 - y, 0.10x + 0.25y = 3.50
