Question 151688
We go Basic Averaging,
{{{(E[1]+E[2]+E[3]+E[4]+E[5]+E[6])/6=82}}}
{{{(84+86+71+91+98+E[6])/6=82}}}
cross multiply,
{{{(6*82)-(84+86+71+91+98)=E[6]}}}
{{{492-430=E[6]}}}
{{{62=E[6]}}} ---------------> score AT LEAST on the final exam to have at least a B grade. If you have this score, you'll have the min. requirement average of 82 for the B grade.
thank you,
