8.96 * 30%
30 ->.3
8.96 * .3 = 2.69
8.96 + 2.69 = 11.65
        
             
        
        
        
About 32 hours (31.9) I believe its just simple addition just with decimals 
I could be wrong though 
        
                    
             
        
        
        
Answer:
x=8
RPS = 36
Step-by-step explanation:
QPS = 180
The two angles that form QPS
QPR + RPS = 180
7x+88 + 3x+12 = 180
Combine like terms
10x+100 =180
Subtract 100 from each side
10x = 180-100
10x = 80
Divide by 10
x =80/10
x = 8
RPS = 3x+12
         = 3(8)+12
          24+12
         36
