Answer: Option 'c' is correct.
Step-by-step explanation:
Since we have given that
We need to find the number of units in order to minimize cost.
We first derivative w.r.t. x,
For critical points:
Now, we will check whether it is minimum or not.
We will find second derivative .
So, it will yield minimum cost.
Minimum cost would be
Hence, At 150 units, minimum cost = $4000
Therefore, Option 'c' is correct.
1/3:no feathers or fur = fish
1/2: 4 legs =bear
1/6: left = birds
1/6 of the animals were birds.
Answer:
x=40
Step-by-step explanation:
x=4(x+10)÷5
x=(4x+40)÷5
5x=4x+40
x=40
Answer:
- Calculus texts: 600
- History texts: 0
- Marketing texts: 0
Step-by-step explanation:
Each Calculus text returns $10/2 = $5 per unit of shelf space. For History and Marketing texts, the respective numbers are $4/1 = $4 per unit, and $8/4 = $2 per unit. Using 1200 units of shelf space for 600 Calculus texts returns ...
$5/unit × 1200 units = $6000 . . . profit
Any other use of units of shelf space will reduce profit.
