Ok, so the first thing you should do is find out how much 1 pound of peaches cost. So you divide 4.20 by 2 pounds and you get 2.10 for 1 pound of peaches. Then you multiply 2.10 by 5 to get 10.50. So 5 pounds of peaches will cost 10.50. Also make sure you include a unit for price. Do 5 pounds of peaches cost $10.50 or 10.50 cats? Including a unit in your answer will keep you from losing valuable points on an exam or assignment. :)
