(A)

we are given for last year

cost of goods sold was $7.5 million and inventory was $1.5 million

firstly , we will find average cost of sold good on week basis

=cost of goods / total number of weeks in a year

so, we get

average cost of sold good on week basis as :

=\frac{7.5}{52}= 0.1442 million

now, we can find weeks supply

Weeks supply=Investment in inventory/ Average cost of sold good on week basis

week supply = 1.5/0.1442 =10

so, week supply = 10 Answer

(B)

we are given for this year

cost of goods sold is $8.6 million and inventory investment is $1.6 million

firstly , we will find average cost of sold good on week basis

=cost of goods / total number of weeks in a year

so, we get

average cost of sold good on week basis as :

=\frac{8.6}{52}= 0.1654 million

now, we can find weeks supply

Weeks supply=Investment in inventory/ Average cost of sold good on week basis

week supply = 1.6/0.1654 =10

so, week supply = 10 Answer

(C)
