Answer:

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

Explanation:

Marks received by Marta in four tests = 86, 84, 97 and 89

Let mark received in fifth test be x

We have average of five test is more than or equal to 90

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.
