The bookstore marked some notepads down from $3.00 but still kept the price over $2.00. it sold all of them. the total amount of money from the sale of the pads was $26.65. how many notepads were sold? what was the price of each notepad?

One way to do this problem is to take 26.65 and divide it by all of the values from $2.01 to $2.99. If one of these goes in evenly with no remainder then that is the cost of each notepad. The quotient (answer when you divide) is the number of pads. Since we can’t have half a pad, the number must go in evenly (leave no remainder).

While we can check each of these, I noticed that 26.65 ends in a 5 and so is divisible by 5 so I decided to check 2.05 as a possible price and it went in evenly. The quotient is 13.

thus, there were 13 notepads and the cost of each is $2.05
