A city bus fare rose from $1.50 in 1995 to $2.25 in 2008. What was the percent increase in the fare?
A33.3%
B50.0%
C75.0%
D66.7%
Answer & Solution
Correct answer: B. 50.0%
1. Find the amount of increase: 2.25 minus 1.50 equals 0.75.
2. The percent increase is the increase divided by the original amount.
3. Divide: 0.75 divided by 1.50 equals 0.50.
4. Move the decimal point two places to the right and add a percent sign: 50.0%.
5. 33.3% is the trap of dividing the increase by the new fare of $2.25 instead of the original $1.50.
