Davids scores on the first three of four 100-point math tests were 86, 92, and 89. What score does he need on his fourth math test to ensure an average score of at least 90?

A. x > 89 

B. x > 93

C. x > 78

D. x > 90

tommo_lcfc · Answer

The sum of the 4 scores must be at least 360 to get an average of at least 90. He has already achieved 267 points, so he needs to get a score of more than 93 to get an average of at least 90.
