The first group orders 3 pizzas and 4 drinks for $33.50. The second group orders 5 pizzas and 6 drinks for $54. Find the cost for each pizza and each drink

Assumptions:

Let the cost of each pizza be p

Let the cost of each drink be d

Givens:

4d + 3p = 33.50

6d + 5p = 54

We have a simultaneous group of equations. To solve this, we can use 3 methods:
