It costs $100 to join a fitness center, plus a monthly fee. You spent $700 last year at the fitness center. How much was the monthly fee? Write and solve an algebraic equation to determine the monthly fee.


  1. Answer:
    Monthly fee is $50
    Step-by-step explanation:
    100 + 12x = 700
    12x = 600
    x = 50
    100 being the initial fee, 12x being the monthly fee (as there is 12 months in a year).

  2. monthly fee is 50. so we started with 700 a year but since it cost 100 to join we minus it from 700 so it will be 600. and since there are 12 months in a year we divide 600 by 12 and that equals 50.
