Question

Lucia's back hurts! She figured out that the books in her backpack are 5 times heavier than the backpack itself. By what percent heavier is the backpack with the books inside, than the books by themselves?

Answer 1

Answer:

120%

Step-by-step explanation:

If the books in the bag are 5 times heavier than the bag itself then the books and the backpack together are 6 times heavier than the backpack itself, so the backpack with the books is (6 ÷ 5) × 100% = 120% heavier than the book by themselves.

Answer 2

Yo sup??

Let the weight of the backpack be y

and weight of books be x, then

x=5y

percentage heavier=((x+y)/x)*100

=6y/5y*100

=120%

Hope this helps.
