You need to convert 3 lb, 6 oz into all ounces. To do this, know that 16 ounces is 1 pound.
(3pounds)(16 oz/1 pound)
This cancels out the pounds, and leaves you with 48ounces, then add the 6 ounces you already knew of. You now have 54 ounces, which is "D"

Answer:

$65
$424500

Step-by-step explanation:

Let x be the price increase.

Then the current price is:

50 + x

Then the number of passengers is:

8000 − 100x

Then the revenue:

Revenue = Price * Number of Passengers
R = (50 + x)(8000 − 100x) =
- 100x² + 3000x+ 400000

This is a quadratic relationship. Maximum point is obtained at vertex.

Vertex is determined by x = - b/2a, find the value of x:

x = - 3000 / (-2*100) = 15

The maximum revenue is:

R = (50 + 15)(8000 − 100 * 15) = 424500
