Answer:
16 ounces of clay he need.
Explanation:
Given:
Reggie had 2-pound bricks of clay and his job is to give 4 ounces of clay to each student.
There are total 28 students.
Now, to get how much ounces of clay does the each student have first we multiply the number of students to the number of ounces of clay.
Number of students × Number of ounces of clay:

Now, total amount of clay ounces Reggie had= 3×32=96 ounces. (1 pound = 16 ounces, 2 pound = 32 ounces.)
So, the total amount of clay he need is =
