Answer:

2  Beetle juices and 3 Potion Punch

Step-by-step explanation:

j = Beetle Juice       cost $2.50

p = Potion Punch      Cost $3

         j + p = 5                      <em>Multiply by -3</em>              -3j  - 3p = -15

$2.50j + $3p = $14           <em>Do not change      </em>+ <em>  </em><u><em> </em></u><u>2.50j  -3p = 14      </u>

                                                                                 - .50j      = -1

                                                                                          j = 2   Beetle Juice

   Substitute into the fist equation and solve for y       j + p = 5

                                                                                         2 + p = 5

                                                                                              p = 3   Potion Punch
