Apple: $0.75

Water bottle: $1.25

Step-by-step explanation:

Let a represent cost of each apple and b represent cost of each water bottle.

We have been given that the cost of 2 bottles of water and 4 apples is $5.50. We can represent this information in an equation as:

We are also told that the cost of 3 bottles of water and 5 apples is $7.50.We can represent this information in an equation as:

From equation (1), we will get:

Upon substituting this value in equation (2), we will get:

Therefore, cost of each apple is $0.75.

Upon substituting in equation , we will get:

Therefore, cost of each bottle of water is $1.25.
