Let’s Practice!
• A chicken spaghetti recipe for
48 costs $138.82 to prepare.
How much is each individual
portion?
• Formula
• Total Recipe Cost ÷ Number of
Portions = Cost Per Portion
• Your recipe for blueberry
pancakes serves 24. You need
to serve the entire middle
school faculty for the teacher
workday breakfast. There are
62 teachers on campus and
they each will eat two
pancakes. What is the
conversion factor for your
recipe?
• Formula
• New Yield ÷ Old Yield =
Conversion Factor
