Answer:
The company collected for 2,430,000 during 2018
Explanation:
We solve using the accounts receivable identity:
[tex]$beginning + sales = ending + collection[/tex]
[tex]$580,000 + 2,400,000 = 550,000 + collection[/tex]
[tex]$ collection = 580,000 + 2,400,000 - 550,000[/tex]
begining receivables  580,000
sales on account    2,400,000
ending  receivables   (550,000)
Collection from customer  2,430,000
