Final answer:
Pizza Hut is offering the better deal as the price per pizza is slightly lower.
Step-by-step explanation:
To determine which restaurant is offering the better deal, we need to compare the price per pizza at each place. Dominos is offering 2 large pizzas for $18.99, which means each pizza costs $9.495.
Pizza Hut is offering 3 large pizzas for $27.99, which means each pizza costs $9.33.
Therefore, Pizza Hut is offering the better deal as their price per pizza is slightly lower.
