Amanda's first four test scores are 77, 95, 84, and 69. What does Amanda need to score on the next test to have at least an 82 average?
A) 85 or greater
B) 90 or greater
C) greater than 85
D) greater than 92

Respuesta :

the right answer is A.
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.
