Answer:
6 Books
Step-by-step explanation:
Let x be the number of books add to fill the box.
Given:
Kylie is packing books into boxes for shipping. Each full box must not be heavier than 6kg
Each book weight = 750g
She has already packed a total of 1,500g.
The full box must not be heavier than 6kg = 6000g.
And she has already fill 1500g.
Therefore, the remaining capacity of the box = Total capacity - used weight
remaining capacity = [tex]6000-1500[/tex]
remaining capacity = [tex]4500[/tex]
The remaining capacity of the box is 4500g.
Each book weight is 750g
So, x = remaining capacity divided by each book weight.
[tex]x=\frac{1500}{750}[/tex]
[tex]x=6[/tex]
Therefore, Kylle add 6 books to fill the box.
