    Question: - If a carpenter charge $825 for 15hr plus $278 for materials ... What is the carpenters rate per hr

    Answer:-

    Now, since we need to find the rate per hour, we divide or set up a proportion.

    825/15 = x/1

    Cross multiply

    825*1 = 825

    15*x = 15x

    15x = 825

    Divide

    15x/15 = 825/15

    x = 825/15

    x = 55

    Now, since they told us that materials are also in the price, we need to add that too.

    $55 per hour + 278 dollars for materials

    55+278 = 333

    But since the rate means how much, we do not need to include any materials cost.

    We have our final answer: $55 per hour

    In this question, there are several information's already given. Let us first write them down for solving the question.

    Amount of money charged by the carpenter for 15 hours = $825

    Then

    Amount of money charged by the carpenter per hour = 825/15 dollars

    = 55 dollars

    So the carpenters rate per hour is $55. The cost of the material has no significance with the carpenters rate per hour. The cost of the material has no significance with the carpenter’s rate per hour. The material cost can change as per the customers need. So it cannot be added to the carpenters per hour rate.
