Evaluate Collision Design Practice Test

A helmet must meet all of these: force < 500 N, weight < 300 g, cost < $30. Test results: Design B = 550 N, 200 g, $25. Based on the data, is Design B acceptable?

A bumper must prevent damage in a 5 mph collision (must-have). Test results: Design A prevents damage but is expensive. Design B is cheap but allows damage. Design C prevents damage and has medium cost. If a school program has a very limited budget but still must meet the damage-prevention requirement, which design is the best choice?
