Question

comic books cost $2 each and magazines cost $4 each. if you want to spend exactly $30 and you buy 3 magazines, how many comic books can you buy? now, use your equation to solve for the value of c, or the number of comic books. you can show your work on zearn if youd like. $2c + 4m = 30$ $2c + 4 \cdot 3 = 30$ $2c + 12 = 30$ $c = \square$

Explanation:

Step1: Subtract 12 from both sides

$2c + 12 - 12 = 30 - 12$
$2c = 18$

Step2: Divide by 2 on both sides

$\frac{2c}{2} = \frac{18}{2}$
$c = 9$

Answer:

$9$
