Question 8 :
A juice mixture has a total volume of 125 liters and is 45% juice by volume. The mixture was created by mixing two different solutions (solution A and solution B). Solution A was 24% juice by volume. Solution B was 64% juice by volume. The volume, in liters, of juice in solution A is equal to a. The volume, in liters, of juice in solution B is equal to b. The numbers a, b and p are all positive constants. If a is p% less than b, what is the value of p?(Round your answer to the nearest hundredth)
