Question 909294
Joseph has scores of 87, 89, and 92 on his first three weekly algebra assessments. 
What score must he get on the Week 4 Assessment to have an average of 90 or better for the four assessments (assume that all four assessments are weighted equally)?
----------------------
Avg for 4 = (87 + 89 + 92 + week4)/4 = 90 (to get 90)
268 + W4 = 360
W4 = 92
