You can't convert miles into gallons those are two different units of measurement.
On September 25.2014 Colson Corp. sold 200.000 widgetrons for 5$ per unit.
200.000*5$=1.000.000$. Same day company was paid for 40% which is 400.000$.
The rest of the money he get paid in two equal parts on November 15.2014 and January 20.2015. So Calson Corp. was paid 300.000$ on November 15.2014 and 300.000$ on January 20.2015.
256.5/18= 14.25
(14.25x2)+(18x2)= 64.5m
The answer is 5 x -3 + 4 x 2 / 2 = -15 + 8 / 2 = -11
2x^2 + 10x + 8
=2( x + 1) (x + 4)
