A group medical practice has 40,000 patients. Charts vary in thickness from 1/4 to 1 inch thick. The average of all charts is 1/2 inch thick. Using the average 1/2-inch thickness, how many inches of shelf space will be required for 40,000 charts? The medical practice uses 48-inch-wide shelving units, which hold 46 inches of files per shelf. There are eight shelves. This means each unit can hold 8 * 46 inches = 368 inches. How many shelving units does the practice need to store its patient records?

I got 20,000 Do I convert that to feet by dividing by 12

If average of 1/2 inch per file, then there would be 2 * 8 * 46 files per unit.

2*8*46x = 736x = 40,000

Solve for x.

To find out how many inches of shelf space will be required for 40,000 charts, you can start by multiplying the average thickness of each chart (1/2 inch) by the total number of charts (40,000).

Average thickness of each chart: 1/2 inch
Total number of charts: 40,000
Total thickness: 1/2 inch * 40,000 = 20,000 inches

So, you are correct that there will be 20,000 inches of shelf space required for 40,000 charts.

Now, to determine how many shelving units are needed, you can divide the total inches of shelf space required (20,000 inches) by the inches that each shelving unit can hold (368 inches). This will give you the number of complete units needed.

Total inches of shelf space required: 20,000 inches
Inches each shelving unit can hold: 368 inches
Number of shelving units needed: 20,000 inches / 368 inches = 54.35 units

Since you can't have a fraction of a shelving unit, you will need to round up to the nearest whole number. Therefore, the medical practice would need 55 shelving units to store its patient records.

Note: You do not need to convert the number of shelving units to feet since the measurement is already in inches.
