Final answer:
Panchito should mix 100 ml of cranberry juice and 50 ml of orange juice to make 150 ml of a 44% cranberry-orange juice blend.
Step-by-step explanation:
To solve this problem, let's set up a system of equations. Let x represent the amount of cranberry juice and y represent the amount of orange juice. We can set up two equations:
x + y = 150 (since the total volume of the blend is 150 ml)
0.7x + 0.05y = 0.44 * 150 (since we want the cranberry-orange juice blend to be 44% cranberry-orange juice)
Solving these equations, we find that x = 100 ml and y = 50 ml. Therefore, Panchito should mix 100 ml of cranberry juice and 50 ml of orange juice.
