Answer:
The increase in cost is
$ 213750
Step-by-step explanation:
From the question we are told that
The marginal cost function is
where ![0 \le x \le 900](https://tex.z-dn.net/?f=0%20%5Cle%20x%20%5Cle%20900)
Since
is in dollars it means that
is the cost price and x is given as the number of bikes now to obtain
for the given increase of the number of bikes we integrate
within the increase limit
This can be evaluated as
![\int\limits^{900}_{450} {C \ '(x)} \, dx = \int\limits^{900}_{450} {700 - \frac{x}{3} } \, dx](https://tex.z-dn.net/?f=%5Cint%5Climits%5E%7B900%7D_%7B450%7D%20%7BC%20%5C%20%27%28x%29%7D%20%5C%2C%20dx%20%20%3D%20%5Cint%5Climits%5E%7B900%7D_%7B450%7D%20%7B700%20-%20%5Cfrac%7Bx%7D%7B3%7D%20%7D%20%5C%2C%20dx)
![C(x) = [ {700x - \frac{x^2}{6} }] \left 900} \atop {450}} \right.](https://tex.z-dn.net/?f=C%28x%29%20%20%3D%20%5B%20%7B700x%20-%20%5Cfrac%7Bx%5E2%7D%7B6%7D%20%7D%5D%20%5Cleft%20%20900%7D%20%5Catop%20%7B450%7D%7D%20%5Cright.)

✓ –28 in simplest radical form is 27!!!
Whoops lol. The answer is 8b³ / c³. Screwed up my work :/
(2b/c)³
= (2bc⁻¹)³
= (2)³ * (b)³ * (c⁻¹)³
= 8b³c⁻³
= 8b³ / c⁻³
