A priter charges $2.85 for binding plus 10 cents per pages for each copy of a community group's annual report. If the report cost was $5.85, the report is how many pages?
Starting with 2.85, if each copy costs 10 cents then 5.85-2.85=3. You have 3 dollars left until reaching 5.85. 30 pages would cost 300 cents or 3 dollars.
