Pt 1 - how much the value goes down each year
Pt 2 - how much the car was originally worth
First, multiply the radius by itself. 5x5=25. Then multiply by pi, or 3.14. 25x3.14=78.5. The area of the circle is 78.5units^2. Hope this helps! ;)
-3 1/2 is rational because the decimal ends at -3.5. It is not sqrt(5) because the decimal never ends and the same follows for pi and 9.23157.

Answer:
- P = 160x +220y
- cost: 50x +70y ≤ 7400
- labor: 20x +25y ≤ 3500
Step-by-step explanation:
As with all cost problems, the total cost is the sum of products of number of items and item unit cost. Here, the items are acres of crops, and their unit costs are the respective cost per acre.
cost: 50x +70y ≤ 7400
Labor hours are added in similar fashion. The unit costs for labor hours are hours per acre for the different crops
labor: 20x +25y ≤ 3500
The profit function follows the same pattern:
P = 160x +220y
