Answer:

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:

#840xxx/100=70#

Multiplying both sides by #100/840#, we get:

#x=70xx100/840#

#x=7000/840#

#x=8.33#
