Answer:
P= 3/13
Step-by-step explanation:
R=7
B=7
Total=14
P(one red marble)=7/14=1/2
P(another red marble no replacement)=6/13
1/2 times 6/13=6/26=3/13
 
        
                    
             
        
        
        
Answer:  The price of each small box is $4.8  and the price of each large box is $10.8.
Step-by-step explanation:
 Let x = Price of each small box, y= price of each large box.
As per given, 
3x+2y= 36  ...(i)
4x+y= 30  ...(ii)
Multiplying 2 to (ii), we get
8x+2y =60...(iii)
Subtract (i) from (iii), we get
5x= 24
x= 4.8
From (ii)
4(4.8)+y= 30
19.2+y=30
y= 10.8
Hence, the price of each small box is $4.8  and the price of each large box is $10.8.

Step-by-step explanation:
If x = the amount of 12% and y = the amount of 20%, then x + y = 80
 
Since we need 80 grams of 15%, 80(.15) = 12.
 
We are given that .12x + .20y = 12. 
 
We can solve the first equation for x or y. Let's do x.
 
x = 80 - y
 
.12(80 - y) + .20y = 12
9.6 - .12y + .20y = 12
.08y = 2.4
 y = 30
 
x = 80 - 30 = 50
