For each of the bookcases a woodworker is building she charges $65 for materials she also charges $35 for each hour she works to build the bookcases how much does the woodworker charge for working 90 hours to build 12 bookcases

How do you think you should solve this problem?

I think you divide

To calculate the total cost of the woodworker's labor, we need to multiply the number of hours the woodworker worked by her hourly rate. In this case, the woodworker charges $35 per hour.

So, to find the cost of 90 hours of work, you simply multiply 90 by $35:
90 hours * $35/hour = $3,150

Therefore, the woodworker charges $3,150 for working 90 hours.

Note: It seems that the cost of materials for building the bookcases is not mentioned in the question. We can calculate the total cost for labor, but we don't have enough information to determine the full cost of building the 12 bookcases.

What would you divide?

I think 65 and 35 and 12

Let's look at the problem step by step.

1. For each of the bookcases a woodworker is building she charges $65 for materials
She made 12 book cases.
How much money does she charge for all of the materials?

2. charges $35 for each hour she works
She works 90 hours. How much does she charge for her labor?
