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:

1. 4d + 3p = 33.50
2. 6d + 5p = 54

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

• Substitution Method
• Elimination Method
• Cramer's Rule

No matter what method we use, we get the same answer:

• d = $2.75
• p = $7.5
