His sales were $7558.82.
Let x be the amount of sales greater than 6500. He earns 5% commission on these sales, which we represent as 0.05x.
Since he earns 3.5% on sales less than or equal to 6500, we can represent this as 0.035(x-6500).
Together, his commission was 415:
0.05x+0.035(x-6500) = 415
Using the distributive property, we have
0.05x+0.035*x-0.035*6500 = 415
0.05x + 0.035x - 227.5 = 415
Combining like terms gives us
0.085x - 227.5 = 415
Add 227.5 to both sides:
0.085x - 227.5 + 227.5 = 415 + 227.5
0.085x = 642.5
Divide both sides by 0.085:
0.085x/0.085 = 642.5/0.085
x = 7558.82
