Brief Exercise 4-09 At Raymond Company, the following errors were discovered after the transactions had been journalized and posted. 1. A collection on account from a customer for $870 was recorded as a debit to Cash $870 and a credit to Service Revenue $870. 2. The purchase of store supplies on account for $1,510 was recorded as a debit to Supplies $1,150 and a credit to Accounts Payable $1,150.

Dr Cash 870

                 Cr Account Receiable 870    

Dr Supplies  360

                  Cr Account Payable    360  

Explanation:

1. whenever sales is recorded, Account receivable is debited and sales revenue is credited,cash is recorded when collection is made against that receivable in this case directly cash has been recorded without first generating account receivable entry.

2.in this case (1510-1150=$360) of purchases has not been recorded therefore we have to create an entry of $360.

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

i believe the answer would have to be a dependable person
