Jay pays a flat fee each month for basic cable service. He also pays $3.50 for each movie he orders during the month. Last month, he ordered 5 movies and his total bill came to $54.
a. Write an equation in point-slope form that represents the total bill, y, in terms of the number of movies, x.
b. Write the equation in slope-intercept form.
c. What is the monthly fee for basic cable service? How do you know?
d. Next month, Jay plans to order 7 movies. What will be his total bill for the month?
e. This month, Jay’s total bill is $78.50. How many movies did he order this month?
a) In terms of point (0,36.5), the equation would be y-36.5=3.5(x-0).
c) The monthly fee is $36.5. We found this by taking the number of movies for a given month (5 movies), multiplying this by the unit price ($3.50), and subtracting this product from the given bill ($54).
e) 12 movies
