Tina buys a loaf of bread for $50, 2oz of ham for $150, and a cake for $200. What percent of the cost is the ham and bread? Let's think first. Chain of thought:
User
The total cost of buying bread and ham was $50 + $150 = $200. Together with the cake, Tina paid $200 + $200 = $400 for the items. Since the total percentage for all the items is 100%, the cost of ham and bread is $200 / $400 * 100% = 50% of the total cost of items.
Therefore, the answer is 50.
