Question

$99 watch with a 40% discount.
I got $247.50 and $39.6 but that's not right.

Answer 1

discount = $ 99(.4) = $39.60

So cost of watch = $ 59.40

(how can you get $ 247 ? . That is 2 1/2 times the original cost !! )

Answer 2

if the price is $99 after the discount, then the full price is 99/.6 = $165 and the discount if $66

If the original price is $99, then after a 40% discount, the price is 99*.6 = $59.40 and the discount is $39.60

You divided $99/.4 = $247.50, but that is not the computation you need.

Answer 3

Notice what happens when you state a problem in a misleading way?

I interpreted that you wanted the cost <b>after</b> a 40% discount.
Steve thought that the $99 was the cost after the 40% discount.

Besides, "$99 watch with a 40% discount. ", is a statement, not a question.
