It takes 40 units of maple sap to produce one unit of maple syrup. jane and her family are bottling maple syrup in 20 oz. bottles. she notices that they add about 2 oz. of air every time they fill a bottle, to avoid overfill. how much maple sap did they need to collect to fill 15 bottles? oz. how much less maple sap did they need than if they would have filled each bottle to the top? express your answer as a negative number. oz.

If it takes 40 units to make one unit of syrup, that means only 2.5% actually ends up as syrup. So if you have 15 twenty ounce bottles then you have a total of 300 .oz you have to fill. (15x20) so if you need 40 times the amount of maple syrup, you must multiply 300 by 40 which is 12,000 .oz of sap. If you filled each bottle up to 18 oz, you would need 270 oz of syrup. It takes 40 times the amount of sap, so multiply 270 by 40 and get 10,800. Your difference between the two would be 12,000-10,800=1,200

Your first answer is 12,000 oz and your second would be -1,200 oz
