At the beginning of the current season on April 1, the ledger of Wichita Pro Shop showed Cash $2,768; Merchandise Inventory $3,500; and Common Stock $6,268. The following transactions were completed during April 2010.

Apr. 5 Purchased golf bags, clubs, and balls on account from Roland Co. $1,555, terms 3/10, n/60
14 Paid Roland Co. in full.

So here's my question, right now I have:

Debit Acc Payable 1,555
Credit Cash 1,508 (rounded to nearest whole dollar)
Credit Purch Disc 47 (rounded to nearest whole dollar)

Is this wrong? Every time I try to answer this question online it keeps telling me that it's wrong. Does this change anything:

7 Paid freight on Roland purchase $93

Is this the algebra:
1,555 - 93 = 1,462 * .03 = 44 (rounded to nearest whole dollar)
then credit purch disc 44 and cash 1,418
then debit accounts payable 1,462?
I am really confused right now because there is another entry like this only that one does not include the whole freight-in entry but the website keeps telling me I'm wrong for that one too. Any advice?
