The science club can spend at most $400 on a field trip to a dinosaur exhibit. it has enough chaperones to allow at most 100 students to go on the trip. the exhibit costs $3.00 for students 12 years and under and $6.00 for students over 12. question: how many students 12 years and under can go if no students over 12 go?

Apinhole camera is made out of a light-tight box with a piece of film attached to one side and pinhole on the opposite side. the optimum diameter d(in millimeters) of the pinhole can be modeled by d=1.9[ (5.5 x 10^-4) l) ] ^1/2, where l is the length of the camera box (in millimeters). what is the optimum diameter for a pinhole camera if the camera box has a length of 10 centimeters
