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.
Divide commission amount by percentage:
83.50 / 0.40 = 208.75
Sales must be $208.75

Step-by-step explanation:
If we know that a odd-numbered disk is selected, we know that the number is 1, 3 or 5.
So, if it is a red disk, is can be number 1 or 3, so we have two possibilities.
If it is a yellow disk, it needs to be number 5, so we have just one possibility.
We have a total of 3 possibilities, and 2 of them are with red disks, so the probability is 2/3 = 0.66 = 66%
