there are 5 testes so when you add up all the points you get 600
90% of 600 = 540 and when you add up on his previous scores you get 344 so now all you have to do is subtract 344 from 540 and you get 196
Hugo need on the final exam to earn a score of exactly 90% is 196.
What is percentage?
To find the percentage, first determine the total amount of what one wants to find a percentage. Divide the number to determine the percentage and lastly multiply the value by 100.
Given are 5 tests.
Total points are 4x 100 + 200 =600
Then, 90% of 600 = 540
The previous scores sum is 82 + 88 + 91 +83 = 344
The score needed to have exactly 90% = 540 -344 = 196
