Oct 25, 2016

The percent of increase in students is 8.33%.

#### Explanation:

The increase in numbers of students at Franklin High School over a five-year period was $910 - 840$ which is $70$.

To find the percent increase, let us consider the percent value as $x$. Since we are calculating the percent increase from $840$ and the increase is $70$, we can write the equation:

$840 \times \frac{x}{100} = 70$

Multiplying both sides by $\frac{100}{840}$, we get:

$x = 70 \times \frac{100}{840}$

$x = \frac{7000}{840}$

$x = 8.33$
