Answer :
Answer with explanation:
Given : The dollar cost of producing x bagels is
[tex]C(x)=300+0.25x-0.5(\dfrac{x}{1000})^3[/tex]
To determine the cost of producing 2500 bagels in dollars.
Put = x= 2500
[tex]C(2500) =300+0.25(2500)-0.5(\dfrac{2500}{1000})^3\\\\ C(2500)=300+625+7.81250=932.81250[/tex]
Hence, the cost of producing 2500 bagels = $932.81250
[tex]C(2501) =300+0.25(2501)-0.5(\dfrac{2501}{1000})^3\\\\ C(2500)=300+625.25+7.8218787505\\\\=933.07187875\approx933.07188[/tex]
Cost of 2501st bagel =[tex]C(2501)-C(2500)[/tex]
[tex]=933.07188-932.81250=0.25938[/tex]
Hence, the cost of the 2501st bagel= $0.25938
