I need this problem and another problem then I should be good, thank you and please. This was due yesterday I´m finishing it right now.

Answer:
$50 a month
Step-by-step explanation:
X= amount per month
(725-125) /12= x
600/12=x
50=x
Answer:
725= 125+ 12x (equation) 50$ (answer). x (variable)
Step-by-step explanation:
725 = 125+ 12x
-125. -125
600 = 12x
12x = 600
divide 12, both sides
x = 50
So $50 dollars each month.
There's a 12 because there's 12 months in a year and it's asking for "each month"
x is the variable and it stands for how much money $ new members pay each month.
