Final answer:
The price of one granola bag is $2.
Step-by-step explanation:
Let's assign variables to represent the prices of the items:
- Let x be the price of one bottle of sports drink
- Let y be the price of one banana
- Let z be the price of one bag of granola
Using the given information, we can create a system of equations:
Equation 1: x + y + 2z = 7.50
Equation 2: 2x + 2y + 2z = 11
Equation 3: x + 3z = 8.50
We can solve this system of equations using substitution or elimination method. Let's use the elimination method.
Multiplying Equation 1 by 2 gives us: 2x + 2y + 4z = 15
Subtracting Equation 2 from this gives us: 0x + 0y + 2z = 4
Simplifying, we get: 2z = 4
Dividing both sides by 2, we find z = 2
Therefore, the price of one granola bag is $2.
