Question

Devin has 32 books to pack in boxes she packs eight books in each box. how many boxes does she need? write an equation using the letter n to stand for the unknown factor. explain. how to find the unknown factor

Answer 1

32÷8=4 boxes
n=4
x+y=n
32÷8=n
x=32
y=8

Answer 2

so 32=(number of boxes) times (number of books per box)
number of books per box=8
number of boxes=n
32=n times 8
so equation is
32=8n

sol divide both sides by 8
32/8=8/8n
4=1n
4=n
4 boxes
