Answer:
6 packs and 9 packs
Step-by-step explanation:
6 packs, 9 packs
The ratio of mechanical pencil to free eraser is <em>2:4, or 1:2</em>.
So that means, for every free eraser you get, you bought the double amount of pencils.
12 free erasers x 2 = <em>24 pencils</em>
18 free erasers x 2 = <em>36 pencils</em>
And a pack of pencils contains 4.
24/4 = 6 packs
36/4 = 9 packs
1572*7=11004
750*125.40=94050
94050-11004=83046
the profit is $83046
