shorty09's comment:
"thanks a lot, I wpould give a lifesaver but I already used it, and cramster won't allow me to give another so I give you the next highest possible points."
Response Details:
Efficiency = Useful Work/Total Energy = 0.100 * 1000 / (0.450 + 0.100 * 1000) = 99.55%
Lifesaver means I answered your question correctly and error-free. Please rate accordingly, I'd be super grateful! Thanks!
