Jones Elementary School has 540 students. If 70% of the students walk to school, then how many students walk to school?

The equation given is: r = log(a/t) + dwe are also given that: time (t) = 4 secondsweakening of earthquake due to distance from epicenter (d) = 2substitute in the equation, we will get: r = log(a/4) + 2graphing the above equation, we would get the graph shown in the attached image.note: i used "x" instead of "a" in writing the equation.hope this : )
