Answer:
The price of a cold drink is 10 dollars.
Step-by-step explanation:
We can use proportion.

So we found out that one ice-cream costs $25.00.
The statement said, "An ice cream costs 15 more than a cold drink"
In other words, A cold drink costs 15 dollars less than an ice cream.
So we would subtract.

So a cold drink costs $10.00.
