Question 210413
you can write an equation for this where 'x' is the score you are asked to determine. Note that to find an average, you add up all the scores and divide by the number of scores.
{{{(80+65+87+75+x)/5=80}}}
Simplifying:
{{{(307+x)/5=80}}}
Solve for x:
{{{307+x=400}}}
{{{highlight(x=93)}}}
