Respuesta :

1995 - 115 bikes
1996 - 130 bikes
1997 - 145 bikes
1998 - 160 bikes

From this we can see that every year the number of bikes increases by 15. So from that we know that...

1999 - 175 bikes 
2000 - 190 bikes 
2001 - 205 bikes 
2002 - 220 bikes
2003 - 235 bikes
2004 - 250 bikes 
2005 - 265 bikes 
2006 - 280 bikes 
2007 - 295 bikes 
 
So in 2007 there will be 295 bikes which is answer choice A. 

Hope this helps! :)
