To get a b in math, alexandria pappas must average 80 on five tests. scores on the first four tests were 8282, 7777, 8181, and 7474. what is the lowest score that she can get on the last test and still get a b?

The scores of Alexandria are 82, 77, 81, 74 and x, the score of the last test.

the average of these 5 is [tex] \frac{82+77+81+74+x}{5}= \frac{314+x}{5} [/tex],

to get a b, the average must be at least 80.

So,

[tex]\frac{314+x}{5} =80[/tex]

314+x=400

x=400-314 = 86

Thus, to get a B, Alexandria must score at least 86 on her last test.

Answer: 86
