Short Answer

Expert verified

Percentage change in the bus fare is50%.

Step by step solution

01

Step 1. Assume the variable for the change in the bus fare,

Let the percentage change in the bus fare =p%

02

Step 2. Form the equation as per statement given in the question,

Question states, "In year 1995,standard bus fare in Chicago was$1.50and in year 2008 fare was $2.25".

Change in fare =$2.25-$1.5=$0.75

Equation for the percentage increase will be,

p%of original amount = 0.75

p100脳1.5=0.75

0.015p=0.75

03

Step 3. Divide the equation by 0.015,

0.015p0.015=0.750.015

p=50%
