Question

The price of a suit is increased by 20% and then reduced by 10%. If the final selling price is $194.40, what was the original price of the suit?

Answer 1

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
