Answer:
He sold a total of 37 albums last month.
Step-by-step explanation:
Given,
Total earned money = $644
Base payment = $200
Additional payment for each album = $12

Total earned money is the sum of base payment and additional payment for each album multiplied with number of albums sold.

Now dividing both side by '12' using division property, we get;
Hence he sold a total of 37 albums last month.
