Answer:
$900
Step-by-step explanation:
<u>Let the fixed salary be x and the commission be y, then as per given, the earnings:</u>
- 10000y + x = 1350
- 15000y + x = 1575
<u>Subtract the first equation from the second:</u>
- 15000y - 10000y = 1575 -1350
- 5000y = 225
then
- 10000y =2*5000y = 2*225 = 450
<u>Using the first equation:</u>
<u>So the fixed salary is</u> $900
