Answer:

an apple costs 0.24 and a pear costs 0.28

Step-by-step explanation:

      3a + 4p = 1.84                                 3a + 4p = 1.84

     -5a + 2p = 1.76   m(-2)               <u>   -10a - 4p = -3.52</u>

        3a + 4p = 1.84

 +<u>   -10a - 4p = -3.52</u>

       -7a          = -1.68

           a         = -1.68/-7

           a        =  0.24

   

       3a + 4p = 1.84

       3(0.24) + 4p = 1.84

       0.72  + 4p = 1.84

                   4p = 1.84 - 0.72

                    4p = 1.12

                      p = 0.28
