Mrs. Fowler’s family was going on a vacation to Disney Worlds. They saved $4500 for the trip. ⅖ of this amount will go to tickets. ¼ of the remaining money will towards souvenirs and snacks at the park. How much $ will be spent on souvenirs and snacks at the park?

The amount of money saved for tickets is $4500 x 2/5 = $<<4500*2/5=1800>>1800.

So, $4500 - $1800 = $<<4500-1800=2700>>2700 is remaining.
$2700 x 1/4 = $<<2700*1/4=675>>675 will be spent on souvenirs and snacks. Answer: \boxed{675}.
