Answer:

A: 15 + 17h = c B: 4 hours

Explanation:

For A you do write the equation by finding your x and your y first

x= $15 fee

y= $17 per hour to clean a house

c= total amount of money charged

For B you can do the problem like this:

You subtract the total amount of money which is $83 by the fixed fee of $15* and then divide your total which is $68 by the amount of money charged per hour which is $17 and you get your answer which is 4 hours.

You can also do your problem like this:

You subtract $83 - $15 to get $68

Then you can multiply $17 per hour by the number of hours that add up to $68 to get your answer.

(No matter what you have to subtract the $83 by the $15)*

Hope that helps you out alot!!!!!
