Final answer:
To determine the number of gizmos produced in a full workday, we multiply the number of gizmos produced per minute by the total minutes in the workday. The correct answer is 720 gizmos, but this option is not listed in the provided choices, suggesting a possible error in the provided information.
Step-by-step explanation:
To calculate the number of gizmos a factory can make in one day, first, we need to determine the total working time. The factory operates from 9:00 am to 5:00 pm which is 8 hours. Since there are 60 minutes in an hour, this translates to 8 * 60 = 480 minutes.
Next, we know the factory can produce 45 gizmos in 30 minutes. To find out how many gizmos can be produced in one minute, we divide 45 gizmos by 30 minutes, which gives us 1.5 gizmos per minute.
Finally, to find the total number of gizmos produced in a full day, we multiply the gizmos produced per minute by the total minutes in the workday: 1.5 gizmos/minute * 480 minutes/day = 720 gizmos/day. Therefore, since the options provided do not include the correct answer, we can conclude that none of the given choices are correct, implying there might be an error in the question or the provided options.
