Floyd is an aspiring music artist. He has a record contract that pays him a base rate of $200 a month and an additional $12 for each album that he sells. Last month he earned a total of $644.

The equation to determine the number of albums (a) Floyd sold last month is:

• 200a + 12 = 644

• 200 + 12a = 644

• 200 + 12a + 644 = 0

• 12a + 644 = 200
