Virty [35]

Answer:

Marta need to score at least 94 to receive an average of 90 or higher considering all five tests.

So we have

$\frac{86+84+97+89+x}{5} \geq 90\\ \\ 86+84+97+89+x\geq 450\\ \\ x\geq 94$

So Marta need to score at least 94 to receive an average of 90 or higher considering all five tests.
