    quadratic word problem :O

    The members of a club hire a coach for the day at a cost of 210$.
    Seven members withdraw which means that each member who makes the trip must pay an extra 1$. How many members originally agreed to go?


    D: no clue how to set it up

    thanks in advance

    (original share) + $1 = (final share)

    let x = original number of members

    \frac{210}{x} + 1 = \frac{210}{x-7}
