Answer:
x is mL of 25% acid and y is mL of 50% acid
We set up 2 equations:
A) x + y = 250
B) .25 x + .50y = .35 * 250 which equals
B) .25x + .50y = 87.50 Multiplying A) by -.5
A) -.5x -.5y = -125 adding the equations we get
-.25x = -37.50
x = 150 mL
y = 100 mL

Information
----------------------------------------------------
Amount = $400
Interest rate = 4% a year
----------------------------------------------------
Equation
----------------------------------------------------
Total amount = 400 + 0.04(400)
Total amount = 400 + 16
Total amount = $416
----------------------------------------------------
Answer: Total Amount = 400 + 0.04(400)
