Sam has \( \$ 7.25 \) and purchases an item for \( \$ 2.25 \). How much money does he have left over? \( \$ \square \)

After Sam purchases the item for \( \$ 2.25 \), we can calculate how much money he has left. He initially has \( \$ 7.25 \). Subtracting the cost of the item gives us \( 7.25 - 2.25 = 5.00 \). So, Sam has \( \$ 5.00 \) left over. To keep it simple, always make sure to line up the decimal points when performing such subtractions! This way, you won't accidentally add or subtract in the wrong place, ensuring accuracy in your calculations.
