Question

Grace bought a dress at a discount of 20%. She spent 2/11 of her salary to buy the dress and had $1008 left. How much does the dress cost before the discount?


Hard question guys - you're a champ if you get this one

Answer 1

1.suppose her salary is= x

>she spent 2/11 of her salary

so dress price is =2x/11

and she left $1008 with her

than-as per question:

$\frac{2x}{11} + 1008 = x$

$x = 1232$

so that we know her salary(x)=$1232

after bought her rest salary was $1008

so we know from it the discounted price of dress was =1232-1008=$224

2.suppose the dress original price was =p

its 20% discounted price was $224

so as per question

$224 + \frac{20p}{100} = p$

$p(dress \: selling \: price) =280$

so that dress original price was=$280

it may help you dear.
