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](https://tex.z-dn.net/?f=%5Cfrac%7B86%2B84%2B97%2B89%2Bx%7D%7B5%7D%20%5Cgeq%2090%5C%5C%20%5C%5C%2086%2B84%2B97%2B89%2Bx%5Cgeq%20450%5C%5C%20%5C%5C%20x%5Cgeq%2094)
So Marta need to score at least 94 to receive an average of 90 or higher considering all five tests.
