Respuesta :

83 is the lowest score that she can get

Answer:

the lowest score that she can get on the las test and still get a B​ is 83

Step-by-step explanation:

x= score needed

(82+76+84+75+x) / 5 = 80

(317+x)/ 5 = 80

Cress multiplication

317 +x = 5 x 80

317 + x = 400

x = 83

317 + 83 = 400

400/5 = 80
