Pls a guy out. tunisia buehrer sells musical instrument and equipment at let it rock in the mall. she earns a commission of 5% on the first 6,000, 7.5% on the next 6,000, and 10% on sales over 12,000. her total sales for the month are 14,640. what is tunisia's total commission?

So the $2640 comes from $14,640-$12,000. Then you simply do:

6000 x .05 = 300

6000 x .075 = 450

2640 x .10 = 264

300 + 450 + 264 = $1014 in total commissions

Hope this helps!

y=3/4x−12.

Step-by-step explanation:

Slope of the perpendicular line is negative inverse: m=34.

The equation of the perpendicular line is y=3x4+a.

To find a, we use the fact that the line should pass through the given point: −12=(34)⋅(0)+a.

a=−12.

Therefore, the equation of the line is y=3x4−12.

If this helps you, please give bainliest!
