We are going to define variables.
 x: number of apples.
 y: number of pears.
 We write the system of equations:
 0.64x + 0.45y = 5.26
 0.32x + 0.39y = 3.62
 Solving the system we have:
 x = 4
 y = 6
 answer: 
 First store: 0.64x + 0.45y = 5.26
 Second store: 0.32x + 0.39y = 3.62 
 Number of apples: 4
 Number of pears: 6
