Question

Eric has $27.00 and wants to buy comic books. If each comic book costs $4.00, create a table and graph the arithmetic sequence to display how much money Eric has left after each comic book purchase. Which graph is an accurate representation of the problem?(1 point)

Four points showing a decrease in money remaining with an increase in number of comic books are plotted on a coordinate plane. The y-axis is labeled money remaining. The x-axis is labeled number of comic books.

Answer 1

Table (number bought n, money left M = 27 − 4n):

- n = 0 → M = 27
- n = 1 → M = 23
- n = 2 → M = 19
- n = 3 → M = 15
- n = 4 → M = 11
- n = 5 → M = 7
- n = 6 → M = 3

Graph: plot the points (0,27), (1,23), (2,19), (3,15) … (6,3) on a coordinate plane with the x-axis = number of comic books and the y-axis = money remaining. The correct choice is the graph that shows money remaining decreasing as the number of comic books increases (y-axis labeled money remaining, x-axis labeled number of comic books) — i.e., the first option described.
