What equation represents the total investment?

• x + y = 5,000

• x + y = 50,000

• x + y = 55,000

• x + y = 60,000

What is the equation for the interest from the 3% investment?

• 0.03x

• 0.04x

• 0.04y

• 0.03y

• 0.04x

• 0.03x

• 0.04y

What substitution is made to eliminate y from the equation?

• y = 55,000 - x

• y = 50,000 - x

• y = 5,000 - x

• y = 60,000 - x
