Final answer:
Julissa ordered 136 powdered doughnuts.
Step-by-step explanation:
To find out how many powdered doughnuts Julissa ordered, we need to subtract the number of doughnuts in other flavors from the total number of doughnuts she ordered.
Let's find the total number of flavored doughnuts:
Plain glazed doughnuts + Chocolate with sprinkles + Jelly-filled doughnuts = (5 + 3 + 6) = 14
To find the number of powdered doughnuts, we subtract the number of flavored doughnuts from the total number of doughnuts ordered:
Total number of doughnuts - Number of flavored doughnuts = 150 - 14 = 136
Therefore, Julissa ordered 136 powdered doughnuts.
