The landscaper pours 200 gallons of herbicide in a pond. The herbicide degrades 10% each week.
How much will be in the pond after 1 week?
200(1.10)^1=220?
Having done a few of these kind of problems for you, it is time for you to tell me what you got for this one
200(0.90)^1=180
It degrades so therefore it goes down Decay....
To calculate how much herbicide will be left in the pond after 1 week, you need to apply the degradation rate of 10% to the initial amount of 200 gallons.
Step 1: Calculate the degradation amount
10% of 200 gallons = 0.1 * 200 gallons = 20 gallons
Step 2: Calculate the remaining amount
After 1 week, subtract the degradation amount from the initial amount.
Remaining amount = Initial amount - Degradation amount
Remaining amount = 200 gallons - 20 gallons = 180 gallons
Therefore, after 1 week, there will be 180 gallons of herbicide remaining in the pond.
