Answer:
The students baked at least 19 pies.
Step-by-step explanation:
We know that each of the pies were cut into 8 pieces. Since the students sold at least 224 pieces of pie, we can use these equations to figure out how many pies were sold and how many were made by the students.
Total number of pies = total number of slices sold/number of slices per pie
Total number of pies = 224/8
Total number of pies = 28
Pies made by students= total number of pies-pies made by school cafeteria
Pies made by students= 28-9
Pies made by students= 19
