10 liters.
20/100 = 5350/5 = 70therefore its 70 dollars
1 dollar is 20 nickles 350/20=17.5 $17.50
Answer: 45% Work: 20 is decreased to 11 9 = D x 20 --- ---- 20 20 20 divided by 9 = .45 .45 as a percent = 45 %
20/100 x 100 = 20 percent
20% of 350 is 70
350 - (20%) = 280
20% of 350 pounds = 350*20/100 = 70 pounds
A pharmacist mixed a 20 percent solution with a 30 percent solution to obtain 100 liters of a 24 percent solution. How much of the 20 percent solution did the pharmacist use in the mixture (in liters).
10 liters.
To find the answer to this, first divide 420 by 350, which is 1.2. Get the percent value of this by multiplying 1.2 by 100, so the percent value must be 120%. Since we are looking for percent change, subtract 100 from that to get 20%. The answer is "350 changes 20% to become 420", or "420 is 20% more than 350".

Initially, there are 36 liters of milk and 4 liters of water in the mixture. To increase the water content to 20%, you would need to add 16 liters of water to make a total of 20 liters of water in the new mixture.
If the price is 20% off, then it is 80% of the full price. So multiply 350 *0.8 = 280.
20/100 = 5350/5 = 70therefore its 70 dollars
