History/Math Extra Credit:
  
Prior to their entry into WWII, the US government passed an act allowing them to sell or lease any defense article to promote the defense of the country.

- $12/gun
 
o
    
Aircraft Radios
 -- $7.50/radio
 
o
    
Telephone Cable 
 
-- $1.65/foot
 
If the US supplied the USSR with 500 machine guns, 325 radios, and 7700 yards of telephone cable, what is the total fee? (2 pts for right answer, 2 extra pts if you can name the act passed by the US government).
