Answer:
Suppose the cost per hour incurred in operating a cruise ship is 3a + b 
dollars per hour, where a and b are positive constants and v is the ship's speed in miles per hour. At what speed (in miles per hour) should the ship be operated between two ports, at a distance D miles apart, to minimize the cost? (Hint: Minimize the cost, not the cost per hour.)
<em>The speed at which the ship would maximize cost is </em>![\sqrt[3]{\frac{3a}{2b} }](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B%5Cfrac%7B3a%7D%7B2b%7D%20%7D)
Explanation:
The problem can be solved using differentiation to get the minimum value of the speed to travel between the two ports. Step by step calculation is contained in the attached images;
Answer:
$160
Explanation:
her net monthly take home pay will be reduced by $200 x (1 - combined tax rate = $200 x (1 - 20%) = $200 x 0.8 = $160
If instead of contributing to her 401k account, Betty took the money home, she would have to pay $40 in taxes (both state and federal), so the net amount that she receives is reduced by the taxes that she pays.
