MATH 1431 Chapter : Bus Calc Hmwk 7 Marginal And Elasticity
Document Summary
Profit = revenue cost xr xp p xr x ( )xc. Marginal functions approximate the effect of the next unit. 2 (a) actual cost to produce 901st disc: Use original equation and determine cost for 900st disc. C(900) = 2000 + 2(900) 0. 0001(900)2 = 3719. Use original equation and determine cost for 901st disc. C(901) =2000 + 2(901) 0. 0001(901)2 = 3720. 82. The actual cost in producing the 901st = 3720. 82 3719 = 1. 82. Use original equation and determine cost for 2000st disc. C(2000) = 2000 + 2(2000) 0. 0001(2000)2 = 5600. Use original equation and determine cost for 2071st disc. C(2001) =2000 + 2(2001) 0. 0001(2001)2 = 5601. 60. The actual cost in producing the 2001st = 5601. 60 5600 = 1. 60 (b) what is the marginal cost when x = 2000. Use derivative equation above and determine cost for 900st disc. Use derivative equation above and determine cost for 2000st disc.
