Faith needs 4 cups of fruit for a smoothie. she already has 78 cup of blueberries and 34 cup of oranges. drag the fruits faith can use to make exactly 4 cups.

We have two fruits so we have following  choices to make exactly 4 cups of fruits:

Blueberry                  Orange

0                                   4    

1                                    3

2                                    2

3                                     1

4                                     0

In case 1: when she is using 4 cup of oranges so no need of blueberry.

In case 2: when she is taking 3 cup of oranges she will use 1 cup of blueberry to get exactly 4 cups of fruits.

case 3: when she is taking 2 cup of oranges she will use 2 cup of blueberries to get exactly 4 cups of fruits.

case 4: when she is taking 1 cup of orange she will use 3 cup of blueberries to get exactly 4 cups of fruits.

case 5: when she is taking 0 cup of orange she will use 4 cup of blueberries to get exactly 4 cups of fruits.
