Hi there, first, we mutliply 1,500 by 10%, 10%=0.1, 1,500*1/10=1,500/10=150, we subtract 1,500 from 150, 1,500-150=1,350. Now, we need to find out what is 30% from 1,350, 1,350*30%=1,350*30/100=1,350*3/10=4,050/10=405. Finally, we subtract 1,350 from 405, 1,350-405=945. Therefore, the answer is $945.
