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

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

let x = original number of members

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