Dr needs 500 needles priced at 2.60 per hundred. If he pays within 10 days, she receives a 2% discount, sales tax 5.5%. What amount would you pay with the discount? My math 2.60 x 500 needles = $13.00 $13.00 x 5.5% = 72cents 13.00 + .72 = $13.72 $13.72  2% = 27cents 13.72  .27 = $13.45 Is this correct? Please show breakdown out of school long time. Thanks

You need to take the 2$ discount before you figure the tax. I get a slightly different answer.
13 * 0.98 = $12.74
12.74 * 1.055 = $13.44
