Question

A retailer has determined that the cost C of
ordering and storing x units of a product is
c=6x+900000/x
(a) Write the expression for cost as a single fraction.
(b) Determine the cost for ordering and storing - x=240
units of this product.

Answer 1

\[Cost = 6x + \frac{900000}{x} = \frac{6x^2 + 900000}{x}\]

Plug in the value of x = 240 units
\[Cost = \frac{6 \times 240^2 + 900000}{240} = \frac{6 \times 57600 + 900000}{240}\]
