2 answers:
77+95+84+69=325
325/4=81.25
This is her average right now
A)77+95+84+69+85=410
410/5=82
B)77+95+84+69+90=415
415/5=83
So B would work too
C)77+95+84+69+87=412
412/5=82.4
(I just chose a number higher than 85)
D)77+95+69+84+95=420
420/5=84
(I just chose a number higher than 92)
A. would be your answer because she at least needs to make a 85 to get a 82 average.
