Solve the problem.The average per-person annual consumption of hot dogs is shown in the table. Let C be the average per-person consumption of hot dogs at t years since 1990. C = 0.97t + 18.41 can be used to model the data.
What is the C-intercept and what does it mean in this situation?
A. (0, 18.41); In 1990 the average consumption was 18.41 hot dogs per-person. B. (-18.98,0); In 2009 the average consumption will be 0 hot dogs per-person. C. (0, 0.97); In 1900 the average consumption was 0.97 hot dogs per-person. D. (0, 18.41); Each year the average consumption is increased by 18.41 hot dogs per person.
