    You would pay 100 dollars to join and then you would pay 30 dollars every month for 4 months. How much would that be?

    For 1 month it would cost $130 because it would be $100 to join + $30 For 2 months it would cost $160 because it would be $100 to join + 2(30) For 3 months it would cost $190 because it would bE $100 to join + 3(30) For 4 months it would cost $220 because it would be $100 to join + 4(30) For 5 months it would cost $250 because it would be $100 to join +5(30) For 6 months it would cost $280 because it would be $100 to join + 6(30) For 7 months it would cost $310 because it would be $100 to join + 7(30) For 8 months it would cost $340 because it would be $100 to join + 8(30)

    But wait!!! $340 is more than $325 so now it more expensive to have a monthly membership. So the answer must be that for 7 months it is cheaper to have the monthly membership

    yeah correct. it's 7, since 4.8 is equivalent to 5, therefor 12-5= 7 nice mertsj. .
