Last year, the number of students enrolled in the school was 672. If this number increases by 12% the next year, how many students will there be?
What an amount is increased by a percent, add the percent change to 100. 100 + 12 = 112. Use the proportion \frac{}{100}=\frac{is}{of} to get \frac{112}{100}=\frac{x}{100}[tex]\frac{112}{100}=\frac{x}{100}[/tex].
