Adriana is planning to ride the public bus to and from school this year. She wants to figure out how much it will
cost her. The bus ride costs $1.25 each direction.

Write an equation that describes the situation. Use x to represent the independent variable and y to represent
the dependent variable.

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
