A research study reports that an average person purchases 160 granola bars per year. If there are 286 million people in the country, how many granola bars are purchased by the whole country in one year?
If on average a person purchases 160 granola bars a year, and there are 286,000,000 people in the country, then the country would purchase:
286,000,000 * 160 = 45,760,000,000.
