Question

jill signed up for a gym membership. her membership costs $35 per month and $12 for every class she takes. if she spent $107 last month how many classes did she take? unknown -> classes taken variable -> c constant -> 35 35 + 12c = 107 multiple-choice question solve the equation. what is the solution? c=-26 c=3 c=12 c=6 rewatch

Explanation:

Step1: Isolate the variable term

Subtract 35 from both sides.
$35 + 12c - 35 = 107 - 35$
$12c = 72$

Step2: Solve for c

Divide both sides by 12.
$\frac{12c}{12} = \frac{72}{12}$
$c = 6$

Answer:

c=6
