Question

Steve has the following scores on the exams for the semester: 96, 85, and 89.  Determine the minimum score Steve needs to make on the fourth exam to have a final average of an “A” (a 93 or better).

anonymous · Answer

(96 + 85 + 89 + x )/4 = 93
(270 + x)/4 = 93 (now multiply the equation by 4
270 + x = 372
x = 372 - 270
x = 102

check...
(96 + 85 + 89 + 102)/4 = 93
372/4 = 93
93 = 93 (correct)

I got 102, but you might need to get a second opinion
