Acoat at a store is originally priced at 54.99.the store marks the price down to 32.99.to the nearest percent ,what is the percent markdown of the coat ?

For this case what we can do is the following rule of three:
 54.99 > 100%
 32.99 > x
 We clear the value of
 x = (32.99 / 54.99) * (100)
 x = 59.99272595
 Therefore, the discount percentage is:
 100-59.99272595 = 40.00727405%
 To the nearest percent;
 40%
 
 The percent markdown of the coat is:
 40%

Hope i can you!
