The cost of tuition at a community college is given by C(x) = 477 + 71x, where x is the number of credit hours. Interpret the slope of this function as a rate of change. A. The tuition at the community college increases by $71 for each additional credit hour. B. The tuition at the community college increases by $477 for each additional 71 credit hours. C. The number of credit hours increases by 71 for each increase of $477 in tuition. D. The tuition at the community college increases by $477 for each additional credit hour.

You just graduated from your local community college and have decided to enroll as a parti-time student (taking fewer than 12 credit hours) at the university. Full-time college work does not fit into your present financial or personal situation. The cost per credit hour at the university is $275 per credit hour. a. What is the cost of a 3-credit-hour literature course? b. Write a symbolic rule to determine the total tuition for a given number of credit hours. Let n represent the number of credit hours taken (input) and T represent the total tuition paid (output). c. What are the possible replacement values for n? d. Complete the table. Suppose you have enrolled in a psychology course and a computer course, each of which is 3 credits. Use the symbolic rule in part b to determine the total tuition paid. f. Use the symbolic rule from part b to determine algebraically the number of credit hours carried by a student with a tuition bill of $1925

The following table shows how much you pay per credit hour when you attend Erie Community College. Number of credit hours | Total tuition cost in $ 0 | 0 1 | 179 3 | 537 8 | 1432 9 | 1611 12 | 2147 15 | 2147 18 | 2147 a. Is the total tuition cost a function of the number of hours taken? Explain using the definition of a function. b. If it is a function, what is the input variable? c. Which variable is the dependent variable? d. If g(t) represents the total tuition cost, interpret the meaning of g(3) = 537. (Write a sentence explaining what it means) e. Is the number of credit hours a function of the total tuition cost? Explain using the definition of a function or an example from the table.

The tuition costs, C, for a local community college are modeled by C(h) = 250 + 200h, where h represents the number of credit hours taken. The local state university has tuition costs, S, modeled by the function S(h) = 300 + 180h. How many credit hours will a student have to take for the two tuition costs to be equal? Round the answer to the nearest tenth of an hour.
