X = amount of the 18% solution
y = amount of the 40% solution
we know the 18% solution has only 18% of alcohol, the rest is maybe water or something, now, how many liters is 18%? well, 18% of anything is just (18/100) * anything, so, 18% of x is just (18/100) *x or 0.18x, and that's how many liters are there.
likewise, how many liters are there in the 40% solution? well, (40/100) * y, or 0.4y, that many.
we know the mixture has to yield 10 liters at 20% alcohol, how many liters of only alcohol is that? well, (20/100) * 10, or 2 liters.


how much of the 40% solution? well y = 10 - x
Answer:
The answer is 45.
Step-by-step explanation:
This number is a multiple of 3 and 5, since it is divisible by both of these numbers.
4 + 5 equals 9, which is what it means by the sum of it's digits.
I hope this helps!

The format is y = mx + b
where y would be your C
x would be your M
m would be the price per mile (2.20)
and b would be your initial fee (2.75)
put this together in that format and we get
C = 2.20M + 2.75

To convert a percent to a decimal, you move the the decimal left two places to convert the percent to a decimal. For example, if you were to convert 14% to a decimal, you move the decimal left two places so that 14% converted to a decimal would look something like this: 0.14
