Question

comic books cost $2 each and magazines cost $4 each. if you want to spend exactly $30 and you buy 7 comic books, how many magazines can you buy? now, use your equation to solve for the value of m, or the number of magazines. you can show your work on zearn if youd like. 2c + 4m = 30 2·7 + 4m = 30 14 + 4m = 30 m = \square

Explanation:

Step1: Subtract 14 from both sides

$14 + 4m - 14 = 30 - 14$
$4m = 16$

Step2: Divide by 4 on both sides

$\frac{4m}{4} = \frac{16}{4}$
$m = 4$

Answer:

$m = 4$
