Answer:
To determine how many cookies Emily had to pass out after one of the students gave their cookies back, we need to analyze the given information step by step.
Initially, Emily had 30 cookies for her birthday. Three students wanted two cookies each, which means they collectively received 3 * 2 = 6 cookies. Therefore, Emily had 30 - 6 = 24 cookies left.
Afterward, a new student arrived and requested three cookies. This means that the new student received 3 cookies from Emily, leaving her with 24 - 3 = 21 cookies.
Next, one of the three kids decided to give their cookies back. Since this child returned their two cookies, Emily now has an additional 2 cookies to distribute. Consequently, Emily's total number of cookies becomes 21 + 2 = 23.
Therefore, Emily had 23 cookies left to pass out after one of the students gave their cookies back.
