Answer: Let x be the number of bottles of lemonade and y be the number of juice boxes.
The cost of x bottles of lemonade is 2x dollars.
The cost of y juice boxes is 0.5y dollars.
The total cost of the drinks is the sum of the cost of the bottles of lemonade and the cost of the juice boxes:
2x + 0.5y ≤ 100
So the correct inequality that models this situation is:
(3) 2x + 0.50y ≤ 100
Therefore, Peter can spend no more than $100 on drinks, which includes the cost of the bottles of lemonade and the juice boxes.
