This storyboard does not have a description.
oh no my ball is flat I need to go buy a pump for my football
lets go to the store to buy one
This pump pushes of air 12 oz for 5.00. the other pump pushes 20 oz 10.00
we need to find the better buy by dividing 5.00 by 12 oz to see price per once just like with the 20 oz divde 10.oo by 20 oz
so divide 5.00 by 12 and get 42 cents per ounce. then the 10.00 divided by 20 oz becomes 5 cents so the 20 ounce is the better buy
Now my foot ball is fixed
yea I found the better buy
