How do you figure out the original price if you have the current price and the amount of the discount?
Take the current price and add whatever the price that was subtracted off from the discount back to it and you will get the original price. If the current price of an item is $50 and had a 10% discount already taken off then dived 50 by 90% (50 / 0.9) which will give you $55.56 which is the original price before the discount. To check to make sure you did it correct take the original price, $55.56, and multiply it by 10% which will give you 55.56 * 0.1 = 5.56 and subtract that from the original; $55.56 - $5.56 = $50 which is the current price. If you have a calculator you can just enter $55.56 - 10% = $50 to check.

How do you figure out a problem that wants to know the original price and gives you the amount of discount?
Let x equal the original price. Let's say the sale is 25 percent off. That means that 0.75x = the sale price. To find the original price, divide the sale price by the decimal equivalent of 100 minus the discount. Example: You bought an item for 48.00 that was marked as being 20 percent off the original price. The original price was 48.00 divided by 0.80 or 60.00
How do you figure two tenths of 1 percent of a dollar amount?
You figure what two tenths of one percent of an amount is by multiplying that original amount by 0.002 The result is two tenths of a percent of that amount.
What is definition of figure of merit of galvanometer?
It is the amount if current it takes for unit deflection in the given galvanometer. k = I/theta Where k is the figure of merit, I is the current supplied and Theta equals the number of divisions of deflection.
How do you find a percentage off if you have the original price and sale price?
Take the sale price from the original price. The difference is the discount. Calculate the discount as a percentage of the original price. This is the 'percentage off'. Example: Original price 100 verdibors Sale price 80 verdibors Discount = 100-80=20 verdibors. So percentage off is 20/100 = 20% ----------------------------------------------------- Calculating percentages: To convert fractions to percentages, multiply the top figure of the fraction by 100, then 'cancel down'. e.g. 1/4 ..... 1/4 x 100= 100/4 = 25 %
How do you calculate a VAT amount of 14 percent from a total amount of 2450?
Divide the 2450 by 1.14 which gives you 2149.12, then subtract that from the original number to reveal the VAT amount of 300.88. This works for any figure you want to remove a percentage from.
What is a discount in finance?
A discount is a reduction of the original price of an item. It can be a percentage or a fixed amount of the original figure. In finance the same principle applies.

How do you figure percent decrease?
(Actual decrease divided by original amount) x100%
How do you figure out 5 percent of a discount?
Multiply the amount by 0.05, or divide the amount by 20. For example, if a shoe store has a sale and they offer a 5% discount, then if you buy a $75 set of sneakers, the discount would be 0.05 * 75 = $3.75 but you can get the same answer with 3.75=75/20. 10
What is figure of merit?
it is amount if current takes for unit diffection in given galvanometer
What are the factors on which the figure of merit of galvanometer depends?
The figure of merit of a galvanometer depends on its sensitivity, which is the amount of deflection for a given current; its damping, which is how quickly the needle returns to zero position after being deflected; and its resistance, which affects the amount of current needed for deflection.
What is definition of figure of merit of galvanometer?
It is the amount if current it takes for unit deflection in the given galvanometer. k = I/theta Where k is the figure of merit, I is the current supplied and Theta equals the number of divisions of deflection.
What happens to the compass needle in Figure 7-11 when the current through the conductor is reversed?
When the current through the conductor is reversed, the magnetic field around the conductor will also reverse. As a result, the compass needle in Figure 7-11 will deflect in the opposite direction compared to when the current was flowing in the original direction.

When you change coordinates of points of a figure to get another figure the original figure is called what?
The original figure is called the pre-image. After the transformation it becomes the image.
What is external resistance?
External voltage is the ration when there is an increase in current and voltage. If you apply voltage to the outside of a circuit and need to figure out the amount of current flow, that would be the external resistance.
