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? (8, 5) is not a solution to the equation. what does that mean in this situation? 2c + 4m = 30 if you buy comic books and magazines, it cost exactly $30.

Explanation:

Step1: Substitute values into equation

Substitute $c=8$, $m=5$ into $2c + 4m$:
$2(8) + 4(5) = 16 + 20 = 36$

Step2: Compare to total budget

Compare result to $\$30$:
$36
eq 30$

Answer:

If you buy 8 comic books and 5 magazines, it does not cost exactly $\$30$. Specifically, this combination would cost $\$36$, which is more than the available $\$30$.
