Answer:
<h2>The factory needs to sell 327 packbacks to make at least 9,800 per week.</h2>
Step-by-step explanation:
We know that each backpacks is sold for $40.00.
The goal is to make at least $9,800 per week. With this information we can define the inequality

Where
represents backpacks. Notice that this inequality is about profits, that's why we subtract the cost from the sell price, in this case, the profid margin is $30.00 per backpack, so

Solving for 

Therefore, the factory needs to sell 327 packbacks to make at least 9,800 per week.
Option A: drop of 8 meters would be correct because a drop in this case indicates something has been removed. -8 equals 8 below 0.
Answer:
letter C is the answer because the answers there are correct exactly
Y=23x-35
so u basically want the slopes to be the same at all times if it’s perpendicular.
Rate of fill-up = 1/44 = 1/44 * 77/77 = 77/3388
Rate of emptying = 1/77 = 1/77 * 44/44 =44/3388
Combined Rate of Fill-up = 77/3388 - 44/3388 = 33/3388 = 3/308
Time for combined fill-up = 308/3 = 102.6667 hours = 102 hours and 40 minutes
