Question

Alysa currently holds an 85 average in her Global class at Edgemont High School. With only three days left in the quarter, two assessments remain. Her 85 average is the mean of her three quizzes that they have had this quarter. Today Alysa will take a test that counts as much as 3 quizzes, and on Thursday she will complete a D.B.Q. that counts as 1 quiz. If she is to receive the same grade on both assessments, what grade does she need in order to earn an 89 for the quarter?

Answer 1

Answer:

Step-by-step explanation:

85+x+x=89

85+2x=89

2x=89-85

2x=4

x=2

So she would need 89+2=91
