If sales revenue is $80 million and accounts receivable increased by $12 million, the amount of cash received from customers is $68 million.
Sales revenue = $80 million
Accounts receivable increased by $12 million - accounts receivable is money that is owned to a business in a form of debt.
Take the sales revenue and subtract the accounts receivable from it, so the amount that was paid to the company by the customers is $68 million.
