Answer:
<h3>
The minimum score speech to get a B+ is 89.</h3>
Step-by-step explanation:
Average of the first 3 = 85 + 77 + 81 / 3
= 243 / 3
= 81
The fourth score ( to get 85 ) = 81 + 89
= 170 / 2
= 85
8/3
divide both sides by 3 and you get x=8/3

1.1x10^6
1100,000

2.468×10^5 = 246,800
the answer is 360 because if you take a third you will have 120 then if you take half of that then you get 60
