Answer:
m=28
Step-by-step explanation:
0.1(0.5m+6)=2
Distribute
.05m +.6 =2
Subtract .6 from each side  
.05m +.6-.6 = 2-.6
.05m = 1.4
Divide each side by .05
.05m/.05 = 1.4/.05
m = 28
 
        
                    
             
        
        
        
Answer:
$16

8 x 2= 16
 
        
             
        
        
        
Answer:
0.3597 = 35.97% probability that roommate A wins the game and thus does not have to wash the dishes.
Step-by-step explanation:
Independent events:
If two events are independent, the probability of both happening is the multiplication of their probabilities.
Rock-paper-scissors rules:
A player that choose rocks beats one who chooses scissors.
A player that choose paper beats one who chooses rocks.
A player that choose scissors beats one who chooses paper.
Probability that roommate A wins the game and thus does not have to wash the dishes.
3 possible events:
Roommate A - Rocks(21% of the time) and Roommate B - Scissors(18% of the time)
So

Roommate A - Paper(39% of the time) and Roommate B - Rocks(61% of the time).
So

Roommate A - Scissors(40% of the time) and Roommate B - Paper(21% of the time).
So

Probability of roommate A winning:

0.3597 = 35.97% probability that roommate A wins the game and thus does not have to wash the dishes.
 
        
             
        
        
        
The answer is c because it makes sense that it would be months.
