x -----> the number of albums Floyd sold last month

The number of albums Floyd sold last month multiplied by $12 for each album plus a base rate of $200 must be equal to the total earned.
Last month he earned a total of $644
so

Solve for x
subtract 200 both sides


Divide by 12 both sides

0.03x+0.035 (5000-x)=155
Solve for x
X=4000 invested at 3%
5000-4000=1000 invested at 3.5%
