A fishery is an area with the specific purpose of controlling fish populations for commercial or recreational fishing. Population dynamics describe how a
fish population changes over time. The population is changed by birth, death,
and migration of fish. While the supply of fish (population growth) can be
modeled with a linear equation, so can the demand of fish (the amount caught).
In one commercial venture, fishermen recorded their daily catch in an ocean
fishery. Using their data, the demand model for the total
number y of fish caught
for x days is y = 349x + 50. What is the meaning of the slope?
What is the meaning of the y intercept?
After 30 days, what is the total number of fish caught?
