Answer:
12 kilograms
Step-by-step explanation:
Let's construct an equation for her profits, we will call it P(x), where x is the number of kilograms produced/sold.
We know she has -$108 profit from buying supplies, and for each kilogram she produces, she earns -$16 (or loses $16, if earning negative money bothers you). However, we also know that she earns $25 per kilogram sold.
Constructing the equation with this information, we get:
Setting this equation to zero and solving for x:
Answer:
The slope is .
Step-by-step explanation:
Choose 2 points on the graph.
(7,3) and (2,2)
Use slope formula:
=
The slope is .
Answer:
The distance between two cities is <em>60 miles.</em>
Step-by-step explanation:
Time taken to travel from B to A = 2 hours
Time taken to travel from A to B = 1.5 hours
Current speed = 5 mph
Let the speed of ferry in still water = <em>u</em> mph
When the ferry moves with the current, it will taken lesser time (i.e. A to B) and when it moves against the current it will take more time (i.e. B to A).
Let the distance between the two cities A and B = D miles
While moving with the current, speed =
While moving against the current, speed =
Formula for Distance = Speed Time
Distance traveled in each case is same i.e. D.
So,
Now,
So, the distance between two cities is <em>60 miles.</em>
