5m + 4m = 72
Combine like terms.
9m = 72
Divide both sides by 9.
m = 8

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
Using the Pythagorean Theorem we can solve this:
20^2 + 6^2 = X^2
400 + 36 = x^2
436 = x^2
x = SQRT(436)
x = 20.9 feet long
