A) Your organization gets half of the revenue after 30% is deducted. You get ...
 (1/2)×($3 - 0.30×$3) = (1/2)×$3×0.70 = $1.05 for each box of cookies

B) If the number you must sell to earn $100 is represented by n, then you have
 $1.05×n = $100
 n = 100/1.05 ≈ 95.24
To earn $100 for your local chapter, you must sell 96 boxes of cookies.
