Mandy wants to buy 100 fruitcakes for her party.
To buy 100 fruitcakes, she would need to buy 10 sets of 10 fruitcakes, as each set of 10 comes with 2 free fruitcakes.
So, she would be paying for 10 sets of 10 fruitcakes, which is a total of 10 * 10 = 100 fruitcakes.
Each fruitcake costs $1.50, so she would have to pay 100 * $1.50 = $<<100*1.5=150>>150 altogether. Answer: \boxed{150}.
