Hope you will understand.

Thank you :)

2.5x

Explanation:

One drink costs for $2.50.

So, if we assume the number of drinks bought to be x and then the total number of drinks bought would be the product of number of drinks bought and the price of each drink.

Therefore, assuming y to be the total cost of drinks bought to be y, we can write the relationship between the number of drinks bought and the cost of drinks as:

y = 2.5x
