It costs 5 cents to copy 3 pages. How many pages can you copy for $\$20$?
I need to figure out how many pages I can copy per dollar, and then multiply that by 20. To find the pages per dollar, I can divide 3 pages by 5 cents, and then multiply by 100 cents per dollar. That gives me 3/5 * 100 = 60 pages per dollar. Now, to find the total pages for 20 dollars, I can multiply 60 by 20. That gives me 60 * 20 = 1200 pages.
