Answer:  $122.50
<u>Step-by-step explanation:</u>
In          Out
8:00    12:00    = 4 hours
12:45    17:30   =<u> 4.75 hours   </u>
           Total        8.75 hours
8.75 hours x $14/hr = $122.50
Note: to subtract 12:45 from 17:30, borrow 1 hour from 17 and add 60 minutes to 30:
  17:30       →         16:90
- 12:45                -<u> 12:45 </u>
                             4: 45
4 hours 45 minutes =  = 4.75 hours
 = 4.75 hours
 
        
             
        
        
        
Answer:
Tamara's example is in fact an example that represents a linear functional relationship. 
- This is because the cost of baby-sitting is linearly related to the amount of hours the nany spend with the child: the more hours the nany spends with the child, the higher the cost of baby-sitting, and this relation is constant: for every extra hour the cost increases at a constant rate of $6.5.
- If we want to represent the total cost of baby-sitting in a graph, taking the variable "y" as the total cost of baby-sitting and the variable "x" as the amount of hours the nany remains with the baby, y=5+6.5x (see the graph attached). 
- The relation is linear because the cost increases proportionally with the amount of hours ($6.5 per hour).
- See table attached, were you can see the increses in total cost of baby sitting (y) when the amount of hours (x) increases.
