Answer:
Mauricio needs 10.5 liters of oil for frying.
Explanation:
It is given that,
Mauricio can fry 6 potatoes using 1 liter of oil.
So, he can fry 18 potatoes using
= 3 liters of oil.
Thus, Mauricio fries 18 potatoes using 3 liters of oil per hour
Now, Mauricio wants to fry the 18 potatoes for 3.5 hours.
So, the total amount of oil needed by him = 3.5 × 3 = 10.5 liters.
Hence, Mauricio needs 10.5 liters of oil for frying.
