25$ is the flat fee.  50$ is the amount charged per hour.  Therefore the equation is C=25+50h where c is the total cost and h is the amount of hours.  

C=25+50h

To find the amount of money for 8 hours simply plug in 8 for h and you get 400.  Don't forget to add the flat fee of 25.  The total cost for 8 hours of service is 425.

To find the amount of money for 10 hours of work, plug in 10 for h and you get 500.  Add 25 to 500 and you get 525 for a total of 10 hours of work.

Hope this helped...

What is the scale factor?
fgiga [73]

Answer:

2

Step-by-step explanation:

Basically you don't need to find x to know the scale factor ,

but I did.So you see that multiple 3 by 2 you will get 6

(MN) and the same will happen with 5.5 and NO (which is 11 btw).

so you can write 2:1
