Answer:
The amount of cash received on January 24 is $3332
Explanation:
The amount of cash received will be for the net amount of receivable after adjusting for sales returns and the sales discount as the payment is received within the discount period of 10 days as stated by the term 2/10 which means a 2% discount if payment is received within 10 days of sale.

The discount received will be = 3400 * 2% =  $68
Thus, the cash received on January 24 will be 3400 - 68  =  $3332
