Part (b)
We use the result of part (a) and plug in (x,y) = (0,0). This is directly from the initial condition y(0) = 0.

-----------------
This means,

is the solution with the initial condition y(0) = 0.
It is prime, it has no factors besides 1,23
You take the orignal price of the video game and subtract the new price to see how much it was reduced. 60-45 = 15. then you take the reduced amount of the game (15) and divide by the original price (60).
you get 25%
your answer is B

In expanded form
200, 000 + 4, 000 = 204, 000
In word form,
Two hundred and four thousand
If your looking for slope Intercept form. y = 2/3x + 6.67. and
y = 2x + 4
