Can an electron in an atom be in an energy level described by the set of quantum numbers n = 5, ℓ = 3, mℓ = −2?

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form

the answer to this is proletariats.

hope this : )
