Answer:
Raw material purchase for the first quearter of 2017: 299.462,54
Step-by-step explanation:
expected sale for second quarter 2016: 22,000 units at $990,000
They grow at 5% each quarter
We are asked for first quarter 2017 which is, three quarter ahead so:
990,000 x 1.05^3 = expected sales for Q1 2017 1,146,048.75
From this: 26% are direct material cost Q1 2017: 297.972,675
but, we already have in our inventory 10% so we need to purchase for:
297,972.675 x (1 - 10%) = 268.175,4075
Plus, a desired ending inventory for 10% of the cost of next quarter:
Q1 2017 x 1.05 = 2017 Q2 = 1.203.351,1875
Then we calculate the material cost:
1.203.351,1875 x 26% = 312.871,30875
And we calcualte the 10% of this:
31,287.130875
In total we need to purchase for:
for expected cost of Q1 2017: 268,175.4075
for desired ending inventory: 31,287.130875
Total purchase: 299.462,538375
