Question

Holly has $10.00 . she saw a purse in a catalog that was marked 14.95 plus 5% sales tax . how much more did holley need to buy the purse

Answer 1

For this case we will first look for the total cost of the purse.
 We then have the following rule of three:
 14.95 $ -----> 100%
 x -------------> 105%
 Clearing x we have:
 x = (105/100) * (14.95)
 x = 15.6975 $
 The amount needed to buy the purse is:
 15.6975 - 10 = 5.6975 $
 Answer:
 holley needs 5.6975 $ to buy the purse
