  1. Was $800 the discounted price or the price before the discount?
  2. And you ask this here why?
  3. Its his/her homework, most likely still at school and doesnt understand the question.
  4. $672

    Cool, but when I went to school we didn't have calculators. lol
  6. You dont need a calculator for this,

    First part is working out the pecentage:

    To do this convert the $800 to 100%=
    800/100 = 8

    Now that we know what 1% is equal to, we need to multiply it by 16 so that we can get the figure for 16%:
    16x8= 128

    So, 16% of $800 is $128

    Now for the second part, we need to take this off the $800 to find what price it was sold for:

    $800
    - $128
    = $672

    When doing maths, its marked similarly to Chemistry, you will get something like 3 or more marks for the working out part and only one mark for the correct answer.
  7. Not having calculators in school when I grew up enabled me to do this simple project in my head. Why would I want to go through all that ?

    Sounds a good way in dealing with such kind of exercises. Never used this way before. You are quite smark. :wahoo:
