Question

this equation and graph represent the situation: comic books cost $2 each and magazines cost $4 each. how many comic books and magazines can you buy with exactly $30? what does the solution of (1, 7) mean in this situation? 2c + 4m = 30 if you buy comic book(s) and magazine(s), it cost exactly $30.

Explanation:

In the equation \(2c + 4m = 30\), \(c\) represents the number of comic books and \(m\) represents the number of magazines. The ordered pair \((1, 7)\) follows the format \((c, m)\), so we substitute these values into the equation to verify: \(2(1) + 4(7) = 2 + 28 = 30\), which matches the total budget. This pair means buying 1 of the item represented by \(c\) and 7 of the item represented by \(m\) uses exactly $30.

Answer:

If you buy 1 comic book(s) and 7 magazine(s), it will cost exactly $30.
