Dave and briana have a total of 82 cds. dave has 15 more cds than briana. how many cds each have?

Respuesta :

azureshades666

Answer:

48.5 for Dave

33.5 for Briana

Step-by-step explanation:

82-15=67

We do this to set aside the 15 extra CDs Dave has.

67/2 is 33.5.

we do this so they have an even share that adds to 67.

2(33.5)+15= 82

This problem is not possible with only whole numbers.
