Final answer:
Andrea needs more information such as the number of students to determine if 4/10 of a pound of chocolate squares will be enough for equal distribution to each student.
Step-by-step explanation:
The question asks us to determine which statement is true if Andrea wants each of her students to have the same amount of chocolate, given that she has 4/10 of a pound of chocolate squares. Without knowing the exact number of students Andrea has, it is impossible to determine if the chocolate will be enough, not enough, or too much. Therefore, the correct answer is b. Andrea needs more information to determine if each student can have the same amount.
To determine if Andrea has enough chocolate for each student, we need to compare the amount of chocolate Andrea has with the amount each student needs. If we know the number of students, we can find out if each student can have the same amount of chocolate. In this case, we only know that Andrea has 4/10 of a pound of chocolate squares, but we don't have information about the number of students. Therefore, we need more information to determine if each student can have the same amount of chocolate. The correct answer is option b. Andrea needs more information to determine if each student can have the same amount.
