Calculate 25% of x: Let x be the previous average.Calculate 25% of x.Expression for current average: x−25%(x)= x−0.25x
Set up equation for current average: We know: Current average is 6 Set up an equation to find x, the previous average. Equation for current average is 6=x−0.25x.
Solve for x: Solve for x.x−0.25x=60.75x=6x=0.756x=8
