You spend at most $10 at the mall you want to buy a book that costs $6.75 and a cold drink how much can you spend on the drink?

You can make an equation: 6.75 + x = 10
6.75 is the amount you spend on the book, x is the amount you can spend on the drink, and 10 is the total cost.

Solve for x to find how much you can spend on the drink.
6.75 + x = 10
Subtract 6.75 from both sides to isolate x.

x = 3.25

You can spend $3.25 on the drink.
