Answer:
Number is 36
Step-by-step explanation:
Let the number be x
one half of the number is
6 subtracted from one half is 12, That is,
3/4 of 120
=3/4*120
=360/4
=90
3/8 of 160
=3/8*160
=480/8
=60
X=original price
increased by 20%
100+20=120
increased by 20% means times 1.20
1.20x is new price
then reduced by 10%
100-10=90
1.20x times 0.90=final price
1.08x=final pricie
given final price=194.40
1.08x=194.40
divide both sides by 1.08
x=180
the original price was $180
