Janelle French · Answer 1

Let x = # of original members

Cost per person (originally) = 832/x

Cost per person after 6 more people = 832 / (x+6)

Solve 832/x=832 / (x+6) + 6 (because the cost was reduced by 6

Solve for x.

x = 26 or - 32 (but x is number of members, so it can't be negative)

# of original members is 26.

Original cost is 832/26 = $32 per person.
