Gil earned these scores on the first three tests in biology this term: 86, 88, and 78. What is the lowest
score that Gil can earn on the fourth and final test of the term if he wants to have an average of at least
83?

Answer 1

Answer: 48

Step-by-step explanation:

86+88+78 = 252

252-300 (mean) is 48

That means the lowest he can get is a 48

Answer 2

The answer would be 80 because 252+x/4 =83 x=80

Hope this helps
