Your answer: q=1.
-
Steps:
1.) Add q to both sides. (11 + q = 12 - q + q.)
2.) Simplify. (11 + q = 12.)
3.) Subtract 11 from both sides. (11 + q - 11 = 12 - 11.)
4.) Simplify again. (q = 1.)

Answer:
$72
Step-by-step explanation:
For the first month, they got a 25% discount, aka $120 off. Now that it's changed to 40%, you need to find how much 40% of $480 is.
480 x .4 = 192
40% of $480 is $192. The next step is to find the difference between $192 and $120.
192 - 120 = 72
Therefore, you need to give them of refund of $72.
