question 12

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) \(x + y = 30,0.05 y + 0.25 x = 3.50\)
