That $ is not needed.

$135 is close, but not correct.

There is more than one way, to calculate the final price. Here are the steps for one way.

1) Calculate 10% of 240, that is, multiply 240 by the decimal form of 10% (which is 0.10)

2) Subtract your result from 240

Now you have the price, after the first reduction.

3) Calculate 40%, by multiplying the new price by the decimal form of 40% (which is 0.40)

4) Subtract your result, like before

Now you have the final price.


EG: A $24.96 shirt goes on sale for 50% off, and you also have a 15%-off coupon.

First, we calculate the 50% reduction. (Symbol * means multiplication.)

0.50 * 24.96 = 12.48

24.96 - 12.48 = 12.48

Next, we calculate a 15% reduction on this new amount.

0.15 * 12.48 = 1.87 (rounded)

12.48 - 1.87 = 10.61

The final price is $10.61

I tend to think what percentage I pay rather than what percent the store gives me off.
If I get a 10% discount off the current price of a $100 item, then I pay 90% of the current price. So after the 1st discount the coat cost .90*$100 = $90
Then the coat has a further 40% discount. So we pay 60% of the current price ($90).
The current price of the coat is now .60*$90=$54

The steps you should take will depend upon what you actually meant. Your lack of capitalization and punctuation allows for differing interpretations. For instance, "the price was decreased by 10% a week later it was marked down by $40%" could mean "The price was decreased by 10% a week; later, it was marked down by 40%" or "The price was marked down by 10%; a week later, it was marked down by 40%".

Which was your meaning? What are your thoughts? What have you tried? Where are you stuck?

Please be complete. Thank you!
