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.
