Afarmer uses pesticides to keep harmful bugs away from his crops. the amount of pesticide used in an inverse variation of the percentage of bugs remaining on the crops. if he uses 5 gallons of pesticide per acre, 5% of the bugs remain. which equation describes this relationship? (let p denote the percentage of bugs and g denote the number of gallons used below.) a. p=1/4g b. p=4g c. p=1/4.g d. p=4/g

Option a p =

Step-by-step explanation:

It is given in the question, amount of pesticides used in an inverse variation of the percentage of bugs, remaining.

If p is the percentage of bugs and g is the gallons of pesticides used.

So  p ∝

or  p =  where k is a constant.

Now it is given that p = 5 gallons per acre and g = 5% of the bugs.

5 =

k = 0.05 × 5 = 0.25

So equation will be

p =

or p = =

Option a is the answer.
