An industrial machine made 63 shirts. If it takes 7 minutes to make each shirt, how many minutes was it working. A. 63+7 B.63-7 C.63x7. My answer is C.

I would also go with letter choice c. :)

Hope I helped

Right.

Thanks alex and Ms. Sue for your help

You're welcome.

To determine the total amount of time the industrial machine was working, we need to calculate the total time taken to make all the shirts.

Given that it takes 7 minutes to make each shirt, we can multiply the number of shirts (63) by the time taken for each shirt (7 minutes):

63 shirts * 7 minutes/shirt = 441 minutes

Therefore, the correct answer is C. 63 x 7 = 441.
