The answer is A; 1/2. You add 1 1/2 and 1 1/2 together to get 3. Then you subtract 3 1/2 and 3 to get your answer 1/2. I hope that helps!
        
             
        
        
        
The initial number of trees is when t = 0:-
1500 * t^0  = 1500   so the answer is either a or c.
The value 1.02 represents a  2% increase  so the  answer is Option c.
        
                    
             
        
        
        
8 < 2b
8/2 < b
4 < b
2b + 15 < 5
2b < 5 - 15
2b < -10
b < -10/2
b < -5
answer is : b > 4 or b < -5

1) y = 1x + 95.50
x = number of bandanas 
2) y = (1 • 50) + 95.50
$145.50 for 50 bandannas 
3) 116.50 = 1x + 95.50
get x by itself 
116.50 = 1x+ 95.50
-95.50 -95.50
21 = 1x
divide by 1
21 = x
 you get 21 bandannas when you pay $116.50
