Final answer:
To find the number of snacks and juices Aisha purchased, we can set up a system of equations. Let's say she bought x snacks and y juices. Since she purchased a total of 19 items, we have the equation x + y = 19. And since she paid a total of $64.25, we have the equation 56.75x + 43.25y = 64.25. Solving this system of equations will give us the values of x and y, which represent the number of snacks and juices she bought.
