/* 
 Cable Revenue Program
 This program calculates the revenue generated from  
 installing coaxial cable, given the number of installations
 and the yards of cable used.  Each installation earns $25
 and each foot of cable earns $2.  For example,
 for input of 3 installations and 15 yards of cable,
 the revenue earned would be $165.
