Answer:

180 gallons

Step-by-step explanation:

In order to calculate you just need to calculate the 10% of the herbicide that is being degraded in the first week, so we do a rule of three to calculate that 10%:

\frac{200}{100} =\frac{x}{10}\\ x=10*\frac{200}{100} \\x=20

So the 10% is 20 gallons, and that is the gallons of herbicide that degraded in the first week, so we just withdraw the 20 gallons degraded from the initial 200 gallons:

200-20=180

So there will still be 180 gallons in the pond after one week.
