Tina used a total of 335 cups of sugar for both batches of cookies, by adding 123 cups for chocolate chip cookies and 212 cups for peanut butter cookies.
The student asked how much sugar was used by Tina for both batches of cookies combined. Tina used 123 cups of sugar for the chocolate chip cookies and 212 cups of sugar for the peanut butter cookies. To find the total sugar used, these amounts need to be added together.
123 cups + 212 cups = 335 cups
Therefore, Tina used 335 cups of sugar in total for both batches of cookies. This exercise is a straightforward example of addition in mathematics, specifically in the context of combining amounts to find a total.
when combining amounts of ingredients, such as sugar in recipes, the values are simply added to find the total amount used. Tina used a combined total of 335 cups of sugar for both types of cookies.
