Question 880215
Mike needs at least a 75% average to pass his math course. The class contains 5 exams that are equally weighted. If he scored a 64%, 86%, 71%, and 90% on the first 4 tests, what score does he need on the final test to earn at least a 75% in the class. Write and solve an inequality.
***
let x=score needed for a 75% average.
{{{((64+86+71+90+x)/5)>-75}}}
{{{(311+x)/5>-75}}}
311+x≥375
x≥64
