Assume that Guardian Company uses a periodic inventory system and has these account balances: Purchases $500,000; Purchase Returns and Allowances $14,000; Purchase Discounts $9,000; and Freight-in $15,000. Determine net purchases and cost of goods purchased.

Net purchases:

= Purchases - Purchase Returns and Allowances - Purchase Discount

= 500,000 - 14,000 - 9,000

= $477,000

Cost of goods sold:

= Net purchase + Freight-in

= 477,000 + 15,000

= $492,000

start by isolating the variable on one side by adding 43w^2 to both sides.   the equation will read:

25w^2+5=0

*subtract 5 from both sides*

25w^2=-5

*divide both sides by 25*

w^2=-1/5

*take the square root of both sides*

w=√(-1/5)

the square root of -1 is i.   the square root of 5 remains √5

the answer is i/√5.

hope this
