Answer:
The correction entries shall be as follows,
1. Service Revenue Dr. $ 920
Customer Account Cr. $ 920
2. Store Purchases Dr. $1,180
Accounts Payable Dr.$340
Supplies Account Cr. $ 1,520
Explanation:
1. The service revenue account was overstated and customer account understated. therefore by debiting service revenue and by crediting customer account, both have been restated at their actual position.
2. The accounts payable was overstated by $ 340 (1,180-1520).it is rectified by debiting with $ 340. Whereas the supplies account was wrongly debited therefore that impact of $1,520 reversed and actual store purchases debited with actual amount of $1,180
