Step-by-step explanation:
Morning is 4 hr 15 min
afternoon is 4 hour 15 min
together is 8 hour 30 min
8.5*14 = 119 dollars
 
        
             
        
        
        
Answer:
the answer is 4%
Step-by-step explanation:
585/12=48.75
50.81-48.74=2.06
now 2.06 that's the money from interest rate 
so now 2.06/50.81=0.04
so the answer is 4%
 
        
             
        
        
        
Answer:
   C.  11
Step-by-step explanation:
Substituting, we have ...
   8{80, 19, 11} ?= 88
   {640, 152, 88} ?= 88
The value from the set that makes the equation true is x = 11.

<em>Alternate methods of solution (other than substitution)</em>
It can be easier to make use of your knowledge of factoring:
   8x = 8·11
   x = 11
Or to make use of your knowledge of numbers (place value):
   8·10 = 80
so x will not be very different from 10.
