total weight of both bags = 3 oz + 20.6m oz
Don's bag = 2 oz
Jamie's bag = 1 oz
Don's marbles = 9.4 oz * m
Jamie's marlbes = 11.2 oz * m
Total weight of Don's bag = 2 oz + 9.4m oz
Total weight of Jamie's bag = 1 oz + 11.2m oz
2 oz + 9.4m oz + 1 oz + 11.2m oz = 3 oz + 20.6m oz

<em>7.5 gallon of gas left</em>
First you need to find out how many cm of water that will be saved after brushing your teeth 3 times.
379 x 3 = 1137
Next you need the convert the cm to liters. You do this by dividing the cm total by 1000.
1137 / 1000 = 1.137
So you would save 1.137 liters of water while brushing your teeth 3 times.
Hope this helps!!
