NEW QUESTION SAME DEAL :HOW DO I SOLVE IT.?
A retailer has some candle sets that cost her $30. If she sells them for $36.60, find her rate of profit based on the cost.

Answer 1

I think what it means by "rate of discount" is percent discount--what percent of the original price the discount was. So first, calculate the discount: $335.00-$154.10 = $180.90. That's the amount of the discount, so now you have to figure out what percent of $335.00 that is.

To calculate this, divide the discount by the original price, then multiply by 100%. 180.9/335 = 0.54. 0.54 * 100% = 54%.

Finally, check your work. He paid a little less than half the original price, so it makes sense that the discount should have been a little more than 50%.

Answer 2

Percent of discount = difference in prices divided by the original price

Difference in prices = 335.00-154.10

Then divide that answer by the original price of 335.00.

You will get a decimal answer so multiply by 100 to convert to a percent.

Hope this helps. Good luck. :)

Answer 3

It's percentages,

154.10 divide 335 times 100 = 46.

So the price he paid was 46% of the full price.

Therefore the discount was 100 - 46 = 54% reduction.

Answer 4

Discount = $(335.00 - 154.10)

Discount rate = Discount/335 X 100%

Answer 5

Divide 154.1 by 335 to obtain the decimal equivelant.
Then multiply the decimal by 100 and attach the % sign

154.10 / 335 = 0.46

0.46 x 100 = 46%

The percent of discount is 46%

Answer 6

discount = 335 - 154.10 = 180.90 dollars
rate of discount = (180.90/335.00)*100 = 54%

Answer 7

154/335=.46 so 54% off

Answer 8

(100-x)/100*335=154.1
hence solve for x
x=54

Answer 9

154.10 / 335 = 0.46 = 46%
