1. On the subway, 8 out of 11 people are carrying a briefcase. Based on this

information, if there are 700 people on the

subway, then about how many do not have a briefcase?

What is the sum of the geometric series in which a1 = 7, r = 3, and an = 1,701? hint: cap s sub n equals start fraction a sub one left parenthesis one minus r to the power of n end power right parenthesis over one minus r end fraction comma r ≠ 1, where a1 is the first term and r is the common ratio
