Question

An article in a shop marked at $240 was sold for $192.
What was the selling price?

Answer 1

selling price? wasn't that 192 $ o.O

Answer 2

I mean what is the discount per cent

Answer 3

ahh.. that makes sense ;)

\[\LARGE 240(1-x\%)=192\]

\[\LARGE 240(1-\frac{x}{100 })=192\]
\[\LARGE 240-\frac{240x}{100 }=192\]
\[\LARGE 240-\frac{24x}{10 }=192\]
multiply both sides by 10
\[\LARGE 2400-24x=1920\]
\[\LARGE -24x=-480 \]

can you solve it from here? :)

Answer 4

Answer 5

20

Answer 6

%%%

Answer 7

Answer 8

Original price: $240
Sale price: $192

\[240-192=48\]

You saved $48 on the product (your discount). Find the percentage of $48 compared to the original price, $240.

\[\frac{48}{240}*100=20\]

So you received a 20% discount.
