On average, every minute of every day, 158 babies are born. The bar graph represents the results of a single day of births, deaths, and population increase worldwide. Exercises 25-26 are based on the information displayed by the graph.
Each day, the number of births in the world exceeds twice the number of deaths by 72 thousand.
a. If the population increase in a single day is 228 thousand, determine the number of birth and deaths per day.
b. If the population increase in a single day is 228 thousand, by how many millions of people does the worldwide population increase each year? Round to the nearest million.
c. Based on your answer to part (b), approximately how many years does it take for the population of the world to increase by an amount greater than the entire U.S. population (315 million)?
