Question 1143037: How many gallons each of 25% alcohol and 5% alcohol should be mixed to obtain 20 gal of 16% alcohol? That equals 3.2 gallons pure, checks.
1. move 78.2 over to the over side. This will give you 287-78.2.
2. when you have .5x = 208.8, divide both sides by .5
3. this should give you x= 417.6
4. make sure to check your work by plugging you answer back into x.

Complete question
<em>18. GOLF Luis and three friends went golfing. Two of the friends rented clubs for $6 each. The total cost of the rented
</em>
<em>clubs and the green fees for each person was $76. What was the cost of the green fees for each person? Define a
</em>
<em>variable, write an equation, and solve the problem.</em>
The variable defined is "y", the equation is 4y + 2(6) = 76 and the value of the unknown variable is 16
Let the cost of green fees per person be y
If Luis and three friends went golfing, this means that 4 people went golfing. The total cost of green fees for all of them will be $4y
If two of the friends rented clubs for $6 each, total amount spent will be $2(6)
The equation that models the statement will then be expressed as;
![4y + 2(6) = 76\\](https://tex.z-dn.net/?f=4y%20%2B%202%286%29%20%3D%2076%5C%5C)
Solve for y
![4y + 2(6) = 76\\4y+12 = 76\\4y = 76 - 12\\4y = 64\\y =\frac{64}{4}\\y = 16](https://tex.z-dn.net/?f=4y%20%2B%202%286%29%20%3D%2076%5C%5C4y%2B12%20%3D%2076%5C%5C4y%20%3D%2076%20-%2012%5C%5C4y%20%3D%2064%5C%5Cy%20%3D%5Cfrac%7B64%7D%7B4%7D%5C%5Cy%20%3D%2016)
The variable defined is "y", the equation is 4y + 2(6) = 76 and the value of the unknown variable is 16.
