Define a variable used in the equation and solve the equation. Hint: 0.25X represents the number of

Respuesta :

Answer: Dark Chocolate = 2.5 lbs, Milk Chocolate = 0.5 lbs

Step-by-step explanation:

                                  Qty           %                        Qty * %

Dark Chocolate:         x             0.25                   0.25(x) = 0.25x

Milk Chocolate:        3  - x          0.75              0.75(3 - x) = 2.25 - 0.75x

           Mixture:           3                                                        100% = 1


Part A:   0.25x + 2.25 - 0.75x = 1

                           2.25 - 0.50x = 1

                          -2.25               -2.25

                                    -0.50x  = -1.25

                                  ÷ -0.50    ÷ -0.50

                                           x  =  2.5

Milk Chocolate: 3  - x    = 3 - 2.5   = 0.5
