Answer:
it's 100
Step-by-step explanation:
9/10 of 1000 is 900, 8/9 of 900 is 800, 7/8 of 800 is 700, 6/7 of 700 is 600, 5/6 of 600 is 500, 4/5 of 500 is 400, 3/4 of 400 is 300, 2/3 of 300 is 200, and 1/2 of 200 is 100 which makes 100 the value of 1/2 of 2/3 of 3/4 of 4/5 of 5/6 of 6/7 of 7/8 of 8/9 of 9/10 of 1000? I hope this makes sense.

100 $;
<span> discount of 20% => 80$;
</span> discount of <span>12%</span>% => 80 - 80*(12/100) = 71.4 $;
100 - (x/100)*100 = 71.4 => x = 29.6 => a single discount of 29.6%;
