Is the average grade of an English class rose from 70 to 85 what is the approximate percent increase
tia_tia [17]

The approximate percent increase in the average grade is 21.43%.

<h3>What is the percentage increase?</h3>

Percentage is a measure of frequency that expresses a number as a value out of hundred. The sign used to denote percentage is%.

Percentage increase = (new grade / initial grade) - 1

(85 / 70) - 1 = 0.2143 = 21.43%
