She has to score at least 86 on her fifth test.

Further explanation:

We will use the average formula to find the fifth value.

Given

Average\ required=80\\x_1=81\\x_2=73\\x_3=84\\x_4=76\\x_5=?

We have to find x5

The formula for average is:

x=\frac{Sum\ of\ values}{Total\ number\ of\ values}\\Here,\\n=5\\So,\\x=\frac{x_1+x_2+x_3+x_4+x_5}{5}\\Putting\ values\\80=\frac{81+73+84+76+x_5}{5}

80*5=314+x_5\\400=314+x_5\\x_5=400-314\\x_5=86

She has to score at least 86 on her fifth test.
