Answer 2

It's wrong... Sorry @coasterman777

Answer 3

if 10000 samples = 1 lb, what is the weight of 100 samples?

let x be the weight of 100 samples (in lbs):

\[\frac{10000 \text{ samples}}{1\text{ lb}} = \frac{100\text{ samples}}{x\text{ lb}}\]Cross multiply to solve for \(x\)
\[10000x = 100\]divide both sides by \(10000\)\[x = \frac{100}{10000} = 0.01\]So 100 samples would weigh \(0.01\text{ lb}\).
