Question

1. the cost $c = 25 + 0.75m$ models a subscription service. which equation solves for $m$?

a $m = \frac{c - 25}{0.75}$
b $m = c - 25 - 0.75$
c $m = c \times 0.75 - 25$
d $m = c - 0.75 \times 25$
priority standard: hsa.rei.b.3 - solve linear equations in one variable.

Explanation:

Step1: Isolate the term with $m$

Subtract 25 from both sides.
$C - 25 = 0.75m$

Step2: Solve for $m$

Divide both sides by 0.75.
$m = \frac{C - 25}{0.75}$

Answer:

A. $m = \frac{C-25}{0.75}$
