Answer:
a. Ship two-day using A
Step-by-step explanation:
The cost = FC +dH
where;
FC = cost of the ship; &

To find, the cost for 2 days,3 days & 9 days rate, we have:
![Cost = 504 + \Big [ 0.30 * (360 ) * (150) * ((2)/(365)) \Big ]](https://img.qammunity.org/2021/formulas/business/college/tl35z1jbwf0v0t01c2fa2h0zre9xm6oto4.png)
Cost = $504 + 88.77
Cost = $592.77
![Cost = 526 + \Big [ 0.30 * (360 ) * (150) * ((2)/(365)) \Big ]](https://img.qammunity.org/2021/formulas/business/college/jvm41hksm83k374xcqj2m9243pq00a34hk.png)
Cost = $526 + 88.77
Cost = $614.77
![Cost = 472 + \Big [ 0.30 * (360 ) * (150) * ((3)/(365)) \Big ]](https://img.qammunity.org/2021/formulas/business/college/ipj34b3r2keszykq7e47dj6tka3py5ecjk.png)
Cost =$472 + 133.15
Cost = $605.15
Also, the cost for 3-days & 9-day rates are calculated and values are tabulated as shown below.
