I am having trouble with this question, please help!

Purchases at a supermarket on a busy Saturday afternoon fall into a roughly normal distribution with mean $55 and standard deviation $18.

How much do the middle 68% of customers purchase (1 standard dev)?


What percentage of people spends more than $73?


What percentage of people spends less than $19?


A purchase of $91 corresponds to what percentile of spending?
