A small bakery sells 2 kinds of cookies. The Monster Cookie sells for $2.25 and the Peanut Butter Deluxe sells for $2.75. Last Monday, cookie sales brought in $268.75 and the bakery sold a total of 109 cookies. How many of each kind of cookie was sold that day?

2.75x+2.25(109-x)=268.75
2.75x+245.25-2.25x=268.75
.50x=268.75-245.25
.50x=23.50
x=23.50/.50
x=47 Peanut Deluxe cookies were sold.
109-47=62 Monster cookies were sold.
Proof:
2.75*47+2.25*62=268.75
129.25+139.50=268.75
268.75=268.75
