A vegetable farmer wishes to switch to a combination of trees and vegetables (agroforestry) on several hectares of her land to reduce erosion and to diversify what she grows. She needs to assess whether her land can produce as much income by growing two crops instead of one. The farmer estimates that the new tree crop would cover 40 percent of her fields, with the vegetable crop covering the other 60 percent. Which equation should she use to calculate how much total income she would get from using the new two-crop plan

Respuesta :

The best equation to show her the income from her plan is (( Tree income per hectare) x total hectares x 0.4) + (( Vegetable income per hectare) x total hectares x 0.6)

Finding the income from trees

Trees will cover 40% of the field. The income would be

= Amount earned from trees per hectare x Number of hectares used by trees

Number of hectares used by trees = 40% x Total number of hectares

Income from trees will be:

= Amount earned from trees per hectare x 40% x Total number of hectares

= Tree income per hectare x 0.4 x Total hectares

Income from vegetables

Applying the same method as above:

= Amount earned from vegetables per hectare x 60% x Total number of hectares

= Vegetable income per hectare x 0.4 x Total hectares

Total income

= Sum of both

= (( Tree income per hectare) x total hectares x 0.4) + (( Vegetable income per hectare) x total hectares x 0.6)
