Problem Solving

Cindy has her eye on a sundress but thinks it is too expensive. It goes on sale for 15% less than the original price. Before Cindy can buy the dress, however, the store raises the new price by 25%. If the dress cost $68 after it went on sale for 15% off, what is the difference between the original price and the final price?

$0.00
$1.00
$3.40
$5.00
$6.80

if x is the original price,

price after 15% discount = (x-0.15x)=68
solving for x, we get x=80

after 25% increase on the discounted price,
new price = 68+68*25/100 = 85

therefore difference in original and new price =$5
(option d)

what is the OA?

$0.00
$1.00
$3.40
$5.00
$6.80

lets say x is the orignal price
>>dress costs 68$ after sale(15% off) that means 85% of x=68
>>orignal price=x=80
>>final price=68+25% of 68 i.e. 85
>>difference = 85-80 = 5

IMO D
