Brenda’s scores on the first three of four 100-point science tests were 95, 92, and 89. What score does she need on her fourth science test to ensure an average score of at least 93?

Answer :

AL2006
If the average of four scores is going to be 93,
then the four scores will add up to  (4 x 93) = 372 .

The first three scores add up to  (95 + 92 + 89) = 276 .

In order to reach a 93 average for four scores,
Brenda needs  (372 - 276) = 96  on the fourth test.
Yay Brenda !  It'll be tough, but you can do it !
