Community Gym charges a $40 membership fee and a $70 monthly fee. Workout Gym charges a $170 membership fee and a $60 monthly fee. After how many months will the total amount of money paid to
both gyms be the same? What will the amount be?

13 months ; $950

Step-by-step explanation:

70x+40 = 60x+170

     -40             -40

70x      =  60x+130

70x      =   -60x

-60x     =   130

10x     = 130

10x/10  = 130/10

13 months

expression #3 is not equivalent. the others are.

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
