Answer:
B (300, 400)
Step-by-step explanation:
The profit maximization will be when the sum of the products will be greater. The maximum profit will be when x is 300 and y is 400. If we put in the equation :
P = 40x + 55 y
A - When x = 0 , y = 500
P = [40 * 0] + [55 * 500]
P = 27500
B -
When x = 300 , y = 400
P = [40 * 300] + [55 * 400]
P = 34000
C -
When x = 380 , y = 200
P = [40 * 380] + [55 * 200]
P = 26200
D -
When x = 400 , y = 0
P = [40 * 400] + [55 * 400]
P = 16000
For simplifying radicals, remember the product rule of radicals: √ab = √a x √b . This radical is simplified as such:
√72 = √9 x √8 = 3 x √4 x √2 = 3 x 2 x √2 = 6√2
In short, the simplified radical of √72 is 6√2.
If you just want to solve for h, as it appears, isolate h by dividing both sides of the equation by 6.25.
That leaves h = 16. (16 hours, presumptively).
4/9 is the simplest ratio......
