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.write an equation to determine the number of albums (a) floyd sold last month.

So he gets paid $200 as a base rate, and $12 dollars more per album sold, so lets name the albums sold x for that we can just plug in whatever number for however many albums have been sold. So now you have 12x+200.
He made $644, so make 12x+200=644, then solve.

I got x= 37.
Plug in to check.
Should be right if you need to solve after.

Dbc if u do the math and stuff that what i got let me know if i was wrong
