A computer system marked $800 is sold at a discount of 16%? and for what price did it sell?

 

[cmichael138]

Was $800 the discounted price or the price before the discount?

And you ask this here why?

Its his/her homework, most likely still at school and doesnt understand the question.

Cool, but when I went to school we didn't have calculators. lol

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.

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 ?
