What’s the question ? & need additional information
Answer:
The problem is stated as:
Min C = 15*(2*x +y) + 21*y
subject to x*y = 450
Step-by-step explanation:
Given that the region is rectangular, it has two opposite sides called x and two other opposite sides called y (both measured in feet). Then, the area (in square feet) is:
A = x*y = 450
One of the sides called y costs $21 per linear foot. The other 3 sides (two x and one y) costs $15 per linear foot. Then, the cost function is:
C = 15*(2*x +y) + 21*y
To estimate an amount to the tenth we have 3 steps to follow: ...
STEP 2: We add the rounded numbers. ...
STEP 1: Round the summands.
STEP 2: Add the rounded numbers.
STEP 3: Look at the total amount of rounding.
We have rounded the two summands down.
The least common multiple of 3, 4, 6, and 8 is 24.
List the multiples out:
3: 3, 6, 9, 12, 15, 18, 21, 24
4: 4, 8, 12, 16, 20, 24
6: 6, 12, 18, 24
8: 8, 16, 24
