Question 629587: the cost of a dozen pencils and 6 pens is 3.34. If 3 pencils cost 0.10, then what is the cost of one pen in cents Answer by 55305(86) (Show Source):
You can put this solution on YOUR website! If 3 pencils cost $0.10 then a dozen(12) pencils must cost $0.40. So now we can subtract that from $3.34 to find the cost of 6 pens. $3.34-$0.40= $2.94, and that is the value of 6 pens. So we should divide by 6 to get the value of 1 pen. $2.94/6= $0.49
So the cost of one pen is 49 cents.
