Respuesta :

Answer

196

Explanation:

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

Thus, Hugo need 196 on the final exam to earn a score of exactly 90%
