Suppose that the total annual consumption of salmon in a certain country is given by $y = 5.75x + 816.9$ and that the total annual consumption of tuna in the same country is given by $y = 1.65x + 837.4$, where consumption is measured in millions of pounds and $x$ is the number of years since 1980. When the country's consumption of salmon reaches its consumption of tuna, what is the annual consumption of salmon

The annual U.S. per capita consumption of cheddar cheese has remained about the same since the millennium, while the consumption of mozzarella cheese has increased. For the years $2000-2010,$ the function $y=0.06 x+9.7$ approximates the annual U.S. per capita consumption of cheddar cheese in pounds, and the function $y=0.21 x+9.3$ approximates the annual U.S. per capita consumption of mozzarella cheese in pounds. For both functions, $x$ is the number of years after 2000 . a. Explain how the given function verifies that the consumption of cheddar cheese has remained the same, while the given function verifies that the consumption of mozzarella cheese has increased. b. Based on this information, determine the year in which the pounds of cheddar cheese consumed equaled the pounds of mozzarella cheese consumed.
