Final answer:
To find the number of tablets needed for the entire prescription, divide the total dose of Skelaxin required by the dose of each tablet. In this case, 15 tablets are needed.
Step-by-step explanation:
To find the number of tablets needed for the entire prescription, we need to determine the total dose of Skelaxin required and divide it by the dose of each tablet. The physician prescribed Skelaxin 400 mg three times a day for 10 days, which means a total dose of 400 mg x 3 times x 10 days = 12,000 mg. Since each tablet is 800 mg, the number of tablets needed is 12,000 mg / 800 mg = 15 tablets.
