Alexis received an 85,89, and 92 on three tests. how many points does she need to score on her next test in order to have an average of at least 90?

94

for her average to be at least 90 then letting x be the score she requires on her next test, then

= 90 ( solve for x )

multiply both sides by 4 to eliminate the fraction

85 + 89 + 92 + x = 360

266 + x = 360 ( subtract 266 from both sides )

x = 94
