Caroline, an employee of Hollister, bought a sweater originally priced at $55 for $38.50 after her employee discount. What percent of change does her employee discount give her?

30% off the original Bc 30 divided by 100 is .3. Then we multiple .3 with the original price who is $55 which gives us 16.5. $16.5 is the discount we got 55-38.50=16.5
