First, we need to find the commission earned on the first $1,500 in sales. Since she earns 6% commission on this amount, her commission would be 6% of $1,500, which is 0.06 * $1,500 = $<<0.06*1500=90>>90.
Next, we need to find the commission earned on the next $2,000 in sales. Since she earns 8% commission on this amount, her commission would be 8% of $2,000, which is 0.08 * $2,000 = $<<0.08*2000=160>>160.
Finally, we need to find the commission earned on the remaining $400 in sales. Since she earns 10% commission on this amount, her commission would be 10% of $400, which is 0.10 * $400 = $<<0.10*400=40>>40.
Therefore, her total commission would be $90 + $160 + $40 = $<<90+160+40=290>>290.
The correct answer is $290.
