1. Cost = room rental + transportation
Let units of cost be "dollars" and let "n" represent the number of people going on the field trip.
.. cost = 637 +18n
.. revenue = 105 +25n

2. You want to find "n" so that revenue matches cost.
.. revenue = cost
.. 105 +25n = 637 +18n
.. 7n = 532
.. n = 76
76 people need to make the trip to break even

Step2247 [10]

$\bf \textit{distance between 2 points}\\ \quad \\
\begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
% (a,b)
A&({{ 6}}\quad ,&{{ 5}})\quad 
% (c,d)
B&({{ x}}\quad ,&{{y}})
