Give the step-by-step reasoning process and then the final answer. Antoine owns a strawberry farm that supplies strawberries to his local bakeries. The first bakery needs 2 sacks, the second bakery needs 4 sacks, and the third bakery needs 12 sacks of strawberries per week. How many sacks of strawberries does he need to supply all the bakeries in 4 weeks?
The first bakery needs 2 x 4 = 8 sacks of strawberries per month. The second bakery needs 4 x 4 = 16 sacks of strawberries per month. The third bakery needs 12 x 4 = 48 sacks of strawberries per month. Therefore, Antoine needs 48 + 16 + 8 = 72 sacks of strawberries to supply all the bakeries for a month.
The final answer: 72.
