When you use a coupon for 15 percent off the original price of a headset you pay 27. What is the original price of the headset Include your equation with the unknown x as well as your answer?
Let the original price be x; The 15% of x is 15/100 × x → the original price less the discount gives the price paid: x - 0.15x = 27 → 0.85x = 27 You can now solve for x. ------------------------------------------- You can also work in percentages: the whole price is 100% The discount is 15% → the amount paid is 100% - 15% = 85% → 85% of x = 27 → 85/100 × x = 27 → 0.85x = 27 as before
Do stores use the original price or the discount price to determine what the tax is?
Stores charge tax on whatever the price that you pay is. So if you are paying a sale price, you should only be paying the tax on the sale price.
How do you use addition and subtraction in a real life situation?
When you go to a store and you add stuff to your shopping cart, and if you have limited money, you should use addition so that you know how much those will cost. Then when it cost more than you thought, you "subtract" the price of a random item by putting it back to the shelf so that the cost would match the amount you have.
