because 100 is our y-intercept since it's 100 when t equals 0. After 1 day, f(t) = 25 because when we plug in 1 in our equation, </span><span>f(t) = 100(0.25)^1 </span>f(t) = 100(0.25) f(t) = 25
Answer: To solve one-step equations, we do the inverse (opposite) of whatever operation is being performed on the variable, so we get the variable by itself. The inverse operations are: Addition and subtraction.
