I need help with this accounting question. Please show all work, thank you!

At the beginning of the month, the accounts receivable subsidiary ledger showed balances for Apple Company $$15,000$ and Berry Company $$7,000.$ During the month, credit sales were made to Apple $$6,000,$ Berry $$4,500,$ and Cantaloupe $$8,500.$

Cash was collected on account from Berry $$11,500$ and Cantaloupe $$3,000.$ At the end of the month, the Accounts Receivable

control account in the general ledger should have a balance of

a$.$ $$26,500$

b$.$ $$12,000.$

c$.$ $$11,500.$
