You have a prescription that calls for 1 cap by mouth three times a day for 10 days. How many capsules are needed?

Question

Can someone show me how to solve this as a word problem for "X"?

Answer 1

OK, Debra, you are not solving for x, but x can be how many days you are taking the Rx.

 

For example, your equation looks like...

 

f(x) = 3x

 

You are taking three capsules a day, so 3 times the number of days.

 

Now, f(10) = 3(10) = 30 capsules needed.

 

Hope this helps!
