Answer:
5 (5x1) , -10 -(5x2), 20(10x2), -40 -(20x2), 80(40x2) 
so the next number should be previous number in the sequence multiplied by 2 and a negative sign.
-`(80x2) = -160
 
        
                    
             
        
        
        
8 children   ($4 x 8 = $32)
2 adults   ($6 x 2 = $12)
2 senior citizens ($3 x 2 = $6)
32+12+6 = 50
        
             
        
        
        
Answer:
c = 4/3
Step-by-step explanation:
3(c + 8) = 28
Since we have paranthesis, first use the dsitributive property [multiply 3 by c and 8]
3(c + 8) = 28
3c + 24 = 28
To find the value of c, you must have c alone on one side, so subtract 24 from both sides
3c + 24 = 28
3c = 4
Now, divide by 3 to both sides to get your answer
3c = 4
c = 4/3
Therefore, the answer is 4/3!
I hope this helps! :)
