Question

At a hospital emergency room, a doctor has determined that for every 15 patients injured from an automobile wreck, 8 were no wearing their seat belts. If the emergency room saw 450 patients last month that were injured from an automobile wreck, what is the best prediction for how many of them were not wearing their seat belt?

Answer 1

Answer

8 out of 15 were found not wearing seat belts in average.

_____________________________

Therefore for a total of 450 people last month,

$\frac{8}{15} \times 450 = 240$

weren't wearing seat belts during the auto mobile wreck.

_____________________________

Therefore 240 people out of 450 weren't wearing seat belts.
