The weight of Jacob's backpack is made up of the weight of the contents of the backpack as well as the weight of the
backpack itself. Seventy percent of the total weight is textbooks. His notebooks weigh a total of 4 pounds, and the backpack
itself weighs 2 pounds. If the backpack contains only textbooks and notebooks, which equation can be used to determinet,
the weight of the textbooks?

Answer

the notebooks are 20% of the overall weight due to 70% being textbooks and the other 6 pounds or 30% being the bag and note books and with 2/3 of 30% being 20% then the text books are 13 pounds i used 4 x 3 1/2 but that's just my guess
