30 pints of first type and 130 pints of second type drinks must be used to make the mixture.
<em><u>Explanation</u></em>
Lets assume, the amount of first type drink is 
pints.
As the total amount of the mixture is 160 pints, so the amount of second type drink 
pints.
The first type is 20% pure juice, the second type is 100% pure fruit juice and the mixture is 85% pure fruit juice. So the equation will be .....
So, the amount of first type drink is 30 pints and the amount of second type drink is (160-30)pints =130 pints.
1) the area of the "side" of the cylinder is A1= pi (4 in).
2) the total area of the circular ends of the cyl. is A2 = 2 pi (2 in)^2 (since the radius of the cyl. is 2 in).
The desired total surface area is A = A1 + A2. Keep "pi;" do not substitute a numerical value for "pi."
1. 3x-10=x+70
+10 -x
2x=80
x=40
2. x+27+2x-39=180
3x-12=180
+12
3x = 180
x = 64
3. 2x ÷ 80=5x+44
- 2x -44
36= 3x
12=x
So i think u subtract how much money the person got and then subtract the answer by his pay.
Truee is right you got it dude
