Amount of decreased water = 3/10
Then, it would be 3/10 * 100 = 30%
So, your answer is 30%
The answer would be 272 because youre trying to find the decrease which is
340x.20 because you always move the percent over two decimals. you would get 68 after multiplying it then u would subtract that number by 340.
2.5x1.30=3.25
4x4.50=18
2x3.75=7.5
3.25+18+7.5=$28.75 total price
2.5+4+2=8.5lb. total weight
28.75/8.5= 3.38 dollars per pound.
