Ariana's total expenses can be calculated by finding the cost of the blueberries and adding the price of the watermelon. Since she bought 2 cartons of blueberries at $3 each, that totals $6. Adding the $5 for the watermelon gives her a total spend of $11. Therefore, the correct expression is \( (2 \cdot \$ 3) + \$ 5 \). In addition to understanding how to combine costs, it’s essential to remember that when you add costs, you’re increasing your total expenditure. Common mistakes include assuming you need to subtract costs—like thinking of it as taking away from a budget—when in fact you're tallying up what you've spent. Always keep that addition in mind when budgeting for groceries!
