a costumer buys 17.01 in gas and requests one five dollar ticket, two one dollar tickets, and one three dollar ticket. he gives
marin [14]

The customer gives you:
-- a  ticket worth . . . . . . 5
-- a ticket worth. . . . . . . 2
-- a bill. . . . . . . . . . . . 100
               ------------------------
-- Total. . . . . . . . . . . . 107

You give the customer:
-- gas worth . . . . . . . . 17.01               
-- a ticket worth . . . . . . 5
-- two $1 tickets worth . 2
-- a ticket worth . . . . . . 3
            ------------------------------
-- Total . . . . . . . . . . . . 27.01

In order to make the trade even, you owe the customer

                               (107.00  -  27.01)  =  <em>$79.99 more
</em>
<em>
</em>You could give it to him in the form of some combination of magazines,
soda, cigarettes, gum, newspapers, motor oil, car deodorizers, candy
bars, washer fluid, anti-freeze, etc.  But he'd be there all day trying to
decide what he wants and making it all add up to exactly $79.99, and
there's a long line of other customers waiting behind him.

That's the beauty of cash money.  You can count out exactly the proper
amount, it only takes a few seconds and bada-bing, he's out of there and
back on the road.

Solve the given differential equation by using an appropriate substitution. the de is homogeneous. (y2 yx) dx − x2 dy = 0
Schach [20]

The solution for the given differential equation is lnlxl = \frac{-x}{y} +C

Given,

(y^{2} +y^{x} )dx - x^{2} dy =0

Here,

x = vy, dx = vdy + ydv

y = ux, dy = udx + xdu

Then,

((ux)^{2} +(ux)x)dx-x^{2} (udx+xdu)=0\\=u^{2} x^{2} dx+ux^{2} dx-x^{2} udx-x^{3} du=0\\=u^{2} x^{2} dx=x^{3} du\\=\frac{x^{2} }{x^{3} } dx=\frac{1}{u^{2} } du

Now,

\int\limits^a_b {\frac{1}{x} } \, dx =\int\limits^a_b {u^{-2} } \, du

lnlxl=\frac{u^{-1} }{(-1)} +C

lnlxl=\frac{-1}{u} +C

y = ux

u = \frac{y}{x}

That is lnlxl =\frac{-x}{y} +C
