I have a question ... hope you guys can help.

There was a purchase order that was sent to a supplier for few goods.

in the purchase order

250 units plant boxes @ unit price cost $2.50 = 625

500 units seedlings @ unit price 1.54.= 770

20 bags potting mixture @unit price 8.50 = 170

The invoice that was sent had these errors

27/5/X0

250 unit plant boxes @ unit price cost $3.50 = $875

500 units seedlings @ unit price 1.54= 770

30 bags potting mixture @ unit price 8.50= 255

Total price $1900

GST $190

Total $2090

now we need to prepare the general journal entries to record the original tax invoice and the tax adjustment that was received from the supplier.

The credit note

250 units plant boxes ( price adjustment) -$1.00/ unit -$250

10 bags potting mixture -$8.50/box - $85...

total $335.00

gst $33.50

Total $368.50

what would be the payment amount and journal entries.

the order question is we need to prepare a cheque requisition and cheque to pay supplier for the purchase made on 27 May to comply with organisation policy.
