It helps to think of a simpler problem. Let's say mpg is 20 and 10% higher on a smooth road.

How many miles will you get with one gallon on a regular road?

How many more miles will you get on a smooth road? 10% more, right? How much is that?

OK - so you've now solved a simpler problem. Use the exact some process to solve your, more complicated, problem.

A 20% acid solution is mixed with 20 liters of a 45% acid solution. How much of a 30% acid solution will result?
vaieri [72.5K]

Answer:

50 liters

Step-by-step explanation:

If x is the volume of 20% acid, then:

x (0.20) + 20 (0.45) = (x + 20) (0.30)

0.2x + 9 = 0.3x + 6

3 = 0.1x

x = 30

30 liters of 20% acid are needed, so there will be a total of 50 liters of 30% acid.
