Question

What was the original price of an MP3 player that is advertised as on sale for 25%

off and the sale price is $60?

can i get an explanation, please :)

Answer 1

• Sold price=60
• Discount=25℅

Now

• Cost price be x.

`\\ \rm\longmapsto 100-25=75\%`

• 75% of x=60

`\\ \rm\longmapsto (75)/(100)x=60`

`\\ \rm\longmapsto x=60* (100)/(75)`

`\\ \rm\longmapsto x=80`

Answer 2

$80

Explanation:

the original price (in percent) = 100%

the discount (25% off) = - 25%

_________________

the sale price (in percent) = 75% =>

equal to $60

so, the original price =

100/75 × $60 = $80
