Apply the process for finding percent change to a real-world scenario. Problem: In 1995, the standard bus fare in Chicago was $$1.50$. In 2008, the standard bus fare was $$2.25$. Find the percent change, rounded to the nearest tenth of a percent. 1. Find the amount of change: Subtract the original fare from the new fare: $2.25 - 1.50 = 0.75$. 2. Find the percent: The amount of change is what percent of the original amount? Let $p$ = the percent. Translate "$0.75$ is what percent of $1.50$?" into the equation: $0.75 = p \times 1.50$. 3. Solve: Divide both sides by $1.50$ to get $p = 0.5$. 4. Convert to percent form: $p = 50\%$. The percent change is a $50\%$ increase.
