How are rational numbers used in day to day life? - Answers

When you are shopping and find a deal on 12 packs of cola advertised at 4 packs for $10. If you don't want to buy all four packs, you find the price of a single pack ($10/4packs = $2.50 per pack) or if you're throwing a party and need 16 packs you find the total cost ($10*4=$40 per 16 packs = 4 groups of 4 packs). You are using rational numbers. Taking it a step further... If all you have is $20, how many 12 packs can you buy? Is how we use algebra in everyday life. What number times $10 gets us $20? 2 and each of those groups are 4- 12 packs so i could get 8- 12 packs total! (our variable is not a letter...its a 12 pack of cola!)
