Answer:
We can calculate the price with both  sales by multiplying the 75.5 units of money by both percentages (to multiply them, we divide them by 100 first):
75.5 * 0.24 * 0.6  10.8
 10.8
 
        
             
        
        
        
3x + 1y = ¹/₃   ⇒ 9x + 3y = 1
2x -  3y = 2²/₃ ⇒ 2x -  3y = 2²/₃
                                 11x = 3²/₃
                                  11     11
                                     x = ¹/₃
                             3x + y = ¹/₃
                         3(¹/₃) + y = ¹/₃
                               1 + y = ¹/₃
                             - 1        - 1
                                     y = ⁻²/₃
                              (x, y) = (¹/₃, ⁻²/₃)
