Write a System of Equations to Describe the Problem Situation $x - y = 30,0.10 x + 0.25 y = 3.50$

Multiple Choice

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) $x - y = 30,0.10 x + 0.25 y = 3.50$
C) y - x = 30, 0.10x + 0.25y = 3.50
D) x + y = 30, 0.05x + 0.25y = 3.50
E) $x + y = 30,0.05 y + 0.25 x = 3.50$
