Molly's family has $3,000 set aside for an upcoming vacation The family plans to spend 3/5 of this amount on gasoline for the drive and motel homes along the way and one half of the remainder on meals how much does Molly's family plan to spend on meals

Molly's family plans to spend 3/5 * $3000 = $<<3/5*3000=1800>>1800 on gasoline and motels.

The remainder of the money is $3000 - $1800 = $<<3000-1800=1200>>1200.
So, Molly's family plans to spend $1200 * 1/2 = $<<1200*1/2=600>>600 on meals. Answer: \boxed{600}.
