For Nina's illness her doctor gives her a prescription for 28 pills. The doctor says that she should take 4 pills the first day and then 2 pills each day until her prescription runs ... How many pills should she take at the end of the 2nd day? ... So how many days will it take for Nina to run out the pill if she takes it as the doctor says.
Please explain in a word problem. I don't understand how to set up one and solve it. Thanks in advance!
