You would have to divide 25 by 4. You would get 6.25. That means that Melinda can babysit for 6 hours.
        
                    
             
        
        
        
A dozen is 12
multiply 5 * 12 = 60
multiply (3/4) * 12 = 9
Then add together
60 + 9 = 69
        
                    
             
        
        
        
Hello from MrBillDoesMath!
Answer:
Domain = { 5. 10. 15. 20}
Range =  -3,-1,1,3}
.
Discussion:
The domain is the set of all "x" values, that is  { 5. 10. 15. 20} and the range is (-3,-1,1,3}
. The arrows in the diagram show the mapping between the domain and the range. For examples, 5 -> 1 ( "x value 5 is mapped to y value 1"),        10 ->3, 15 ->-3, and 20 -> -2
Thank you,
MrB
