Let N be the number of notebooks that the paper company can produce in 12 days. We can set up a proportion to solve for N:
4,000 notebooks / 4 days = N notebooks / 12 days
To solve for N, we can cross-multiply and simplify:
4,000 notebooks * 12 days = 4 days * N notebooks
48,000 notebooks = 4N
N = 48,000 notebooks / 4
N = 12,000 notebooks
Therefore, the paper company can produce 12,000 notebooks in 12 days!!
