how to calculate government tax revenue

how to calculate income elasticity of demand (em)
em = (change Qd/change M)* (M/Qd)
positive = normal, neg = inferior
normal goods = more than 1 = lux, less than 1 = necessity
how to calculate cross price elasticity of demand
exy = (change Qdx/Change Py) * (Py/Qdx)
negative = complements, positive = subs
how to calculate price elasticity
ep = |(change Qdx/change Px) * px/Qdx)|
elasticity
steeper demand curve = more inelastic
flatter demand curve = more elastic
