Answer:
The amount with Dakota = $0.421
The amount with Ethan = $8.421
Step-by-step explanation:
Let the Initial amount with Dakota be 'x'
Therefore,
Amount with Ethan = x + $8
After giving of money to the Dakota i.e
of ( x + $8)
Amount available with Dakota = x +
=
Amount available with Ethan = (x + $8) -
=
Now,
or
or
2(3x + 24) = 5(5x + 8)
or
6x + 48 = 25x + 40
or
25x - 6x = 48 - 40
or
19x = 8
or
x = $0.421
Hence,
The amount with Dakota = $0.421
The amount with Ethan = x + $8
= $0.421 + $8
= $8.421
For this case we have the following function:
The first thing you should do is graph the function to see the behavior.
When observing the graph (in the attached image) we observe that the following point belongs to the graph:
To prove it, let's evaluate the point in the function:
The equation is fulfilled and therefore the point belongs to the graph.
Answer:
(6.2, 7.4)
