A man bought a TV set that was listed at $160. He was given successive discounts of 20% and 10%. The price he paid was ?

Question

anonymous · Answer

((($160) * (20% / 100)) * (10% / 100)) = ?

Remember 20% is the same thing as twenty 100ths or 0.20, 10% is 0.10

cwrw238 · Answer

a 20% discount means new price is 80% of $160
so multiply 160 by 80/100
then multiply this result by (100-10) = 90%  that is 90/100

the answer should be 115.2

cwrw238 · Answer

(160 * 80 ) / 100 = 160 * 0.8 =    $ 128
128 * 0.9 =       $ 115.2

note 80/100 = 0.8 and 90/100 = 0.9
