X = total amount of people
80% of x = 540
.8x = 540
x = 675
There were 675 people

Answer:
x=9
Step-by-step explanation:
given;
x\y = 3\4
to find;
x\12=?
solution;
using both equations,
3\4=x\12
by cross multiplication,
36\4=x
9=x
x=9
You could simplify 255
100+100+55
for each hundred there's 15$ earned so 15×2 =30$
there's 55 left and 1 till 99 =0.10 each
55×0.10=5.5$
30+5.5=35.5
in short the answer is 35.5$
