Answer:
Step-by-step explanation:
Let p be the number of trees Wangari plants, and h be the time she spends planting them in hours.
We have been given that Wangari plants trees at a constant rate of 12 trees every 3 hours.
Let us find number of trees planted in 1 hour by dividing 12 by 3.


We can represent this information as: 
Therefore, the equation
relates the number of trees (p) Wangari plants, and the time (h) she spends planting them in hours.
We let C be the cost
x be the number of loaves
cost = overhead cost+ cost to bake - selling price
cost = 90 + 0.60x - 1.50x
cost = 90 - 0.90x
