Prevalence is a measure of disease that allows us to determine a person's likelihood of having a disease. Therefore, the number of prevalent cases is the total number of cases of disease existing in a population. A prevalence rate is the total number of cases of a disease existing in a population divided by the total population. So, if a measurement of cancer is taken in a population of 40,000 people and 1,200 were recently diagnosed with cancer and 3,500 are living with cancer, then the prevalence of cancer is 0.118.
1 Canned food or frozen raw food, on average, costs between $400 and $1,000 per year for one to three cases of 13-ounce cans per month or for one to three 10-pound bags of frozen raw food per month.

The average household consists of 2.5 people, who spend $6,602 on food per year. Letâs assume that a person eats three meals a day, 365 days a year. That adds up to 2,737.5 meals a year for that average family. In other words, the average American spends $2.41 per average meal. Now, letâs say that average American family can shave just $0.10 off of their average meal.
