Answer:
5.6 gallons.
Step-by-step explanation:
If we take x gallons of 25% grape juice then it will contain
gallons of pure grape juice.
Again, if we take y gallons of 75% grape juice then it will contain
gallons of pure grape juice.
If we mix them then the total volume will become x + y = 7 gallons ...... (1)
Again the mixture will become 35% juice.
So,
⇒ 0.25x + 0.75y = 0.35x + 0.35y
⇒0.1x = 0.4y
⇒x = 4y........ (2)
Now, solving equations (1) and (2) we get, 5y = 7, ⇒ y = 1.4 gallons
Hence, x = 4y = 5.6 gallons
Therefore, the 25% grape juice was mixed by 5.6 gallons. (Answer)
<span>I found the following about exponential notation at this site:
http://www.vendian.org/envelope/dir0/exponential_notation.html
"Exponential notation lets you move the decimal point in a number. It
simplifies numbers by getting rid of zeros, and making math easier. Getting
rid of zeros helps with big 100,000,000 and small 0.000,000,001 numbers.
