When a weed solution is added to a lawn, the number of weeds can be represented by the function W(d)=1500(.75)^d where d is the number of days since application. By what percent does the population of weeds decrease each day

Number of weeds is represented by the function,

-------(1)

Here, Number of days since application

Function representing the exponential decay is,

--------(2)

Initial value

Percentage decay

duration

By comparing both the functions (1) and (2),

0.25 ≈

Or 25%

Therefore, population of weeds will decrease 25% each day.
