in order for brady to earn a b in his biology course, his test scores must average at least 80%. on the first 5 tests, he has an average of 77%. there is one test remaining in the course. what is the minimum score brady needs to earn on the last test to score a b in the class?

Respuesta :

84 on the test. hope this helps
average at least 80%. on the first 5 tests = 80 x 5 = 400
average of 77%. there is one test remaining in the course so 77 x 4 = 308
400 - 308 = 92
minimum score Brady needs to earn on the last test to score a B in the class is 92
