Answer:
recipe conversion factor RCF = 4 portion
so correct option is D. 4
Step-by-step explanation:
given data
recipe makes = 6 ten-ounce portions
required make = 30 eight-ounce portions
to find out
recipe conversion factor (RCF)
solution
here Recipe make is = 6 × 10 = 60 portions
and required make = 30 × 8 = 240 portions
now we apply here recipe conversion factor RCF that is express as
recipe conversion factor RCF = (required make) ÷ (recipe make) ..................1
put here value we get
recipe conversion factor RCF =

recipe conversion factor RCF = 4 portion
so correct option is D. 4
