If you are charging 5 per hour use h to determine how many hours and add 10 for the connection fee
5h+10
I hope this helps you
if he can earn $9 per hour
$405 ? hours
?=405/9
?=45 hours he worked
The amount of work done by Kalon in an hour is equal to 1/4. This is based on his time to finish the job. Letting x be the number of hours Marna can finish the job alone will let her finish 1/x of the job in an hour. If their rates are added together and multiplied by the number of hours they worked together, the product should be one whole job.
(1/4 + 1/x)(1 5/7) = 1
The value of x is 3. Therefore, it will take 3 hours for Marna to clean the chimney alone.
302.1 is the answer to the problem.
