Question

a shop allows a discount of 10% on cash purchase. A customer paid $126.00 for a wristwatch . calculate the marked price of the wristwatch​

Answer 1

Explanation:

Let
`p` be the price of the watch:

`10\%` of
`p` is the amount of discount received. S0,

`p-(10)/(100) p=126`

`p-(1)/(10) p=126`

`(9)/(10) p=126`

`9p=1,260`

`p=(1,260)/(9)=\$140`

The marked price of the wristwatch​ was $140.

CHECK: 10% of $140 = $14 $140-$14 = $126
