The percent of increase in students is $8.33 %$ $8.33%$ .

Explanation:

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

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

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

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

$x = 70 \times \frac{100}{840}$ $x=70xx100/840$

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

$x = 8.33$ $x=8.33$
