It gives you the number of product units you get per dollar spent.
To calculate a 20% discount on a price of $18.50, you first convert 20% to a decimal by dividing by 100, which gives you 0.20. Then, you multiply the price by the decimal to find the discount amount: $18.50 x 0.20 = $3.70. Finally, subtract the discount amount from the original price to find the discounted price: $18.50 - $3.70 = $14.80.
Discount divided by original price gives you a decimal which you then multiply by 100. This equals percent of discount Eg: $15 discount, $80 original price 15 / 80 = 0.1875 x 100 = 18.75%
To take 30 percent off of a price, first convert the percentage to a decimal by dividing by 100, which gives you 0.30. Then, multiply the original price by this decimal to find the discount amount. Subtract the discount from the original price to get the final price after the discount. For example, for an item costing $100, a 30 percent discount would reduce the price by $30, resulting in a final price of $70.
Cost price divided by selling price then multiply by 100 Eg. Cost price £5 divided by selling price £20 equals £0.25, multiplied by 100 equals 25%
Sale price/original price will give you a fraction. The fraction x100 gives you the percentage that the sale price is of the original price.100-(that percentage) gives the percent taken off.
Dividing the units by price will give you the number of units that each cent or dollar will buy. In comparing prices, this is less useful than determining unit price.
You calculate the arc elasticity of a commodity by dividing the change in demand by the average price, and then dividing that answer by the change in price divided by the average demand. So you will have (change in demand/average price)/(change in price/average demand).
You seem to be saying that 15% off gives a discounted price of 680, and asking what the original price was before the discount. Since the price was discounted by 15%, the discounted price is 85% of the original price. Dividing 680 by 0.85 gives 800 as the original price.
To find the price per kilogram, you would divide the total cost by the weight of the oranges. In this case, $7.50 divided by 5 kg equals $1.50 per kilogram.
Dividing the change in demand for the product by its change in price. e=(change in demand)%/(change in price)%
by dividing current year price to base year price
The gross profit percentage is calculated by finding the difference between the selling price and the cost price, dividing it by the cost price, and then multiplying by 100%. In this case, the gross profit is 2.20 - 1.65 = 0.55. Dividing this by the cost price of 1.65 gives 0.3333. Multiplying by 100% gives a gross profit percentage of 33.33%.
$67. Arithmetic will solve this. x-x*0.2 = 53.6, where x is the original sale price. Simplifying gives x*(1-0.2) - 53.6 or x*(0.8) = 53.6. Dividing the 0.8 through gives x = 67. Finding a reduced price is simply subtracting the original price multiplied by the discount (in fraction form from the original price.
