Michelangelo decided to order Pizza Hut last night. He purchased 3 pizzas and 2 orders of breadsticks for a total of $29.50. Donatello ordered 2 pizzas and 3 orders of breadsticks last Sunday for a total of $23. Set up a system. Let "p" represent the price per pizza and "b" represent the price of an order of breaksticks.

3p + 2b = 29.50
2p + 3b = 23

3p + 2b = 23
2p + 3b = 29.50

3b + 2p = 29.50
2b + 3p = 23

5bp = 29.50
5bp = 23
