The price of phone is stated, taking the price of the phone as p and the discount on sale as 20%
Answer:
0.848p
Step-by-step explanation:
Price of phone = p
Sales tax = 6%
Discount on sale = 20%
With a 20% discount, the discounted price of the phone will be :
100%p - 20%p = 80%p = 0.8p
The sales tax will increase the price thus ;
0.8p + 6% of 0.8p
0.8p + 0.06 * 0.8p
0.8p + 0.048p
The cost of the phone including tax becomes ; (0.8p + 0.048p) = 0.848p
The complete question is missing, so i have attached it.
Answer:
x = 9(sin 42)/(sin 29)
Step-by-step explanation:
We want to find an expression for x.
From the attached image, we can see a triangle with 2 angles given and 2 sides to be 9 and x respectively.
Now, the law of sines says that;
A/sin A = B/sinB = C/sin C
So applying it to this question, we have;
x/sin 42 = 9/sin 29
Thus,
x = 9(sin 42)/(sin 29)
Discounted price = 24
discount rate = 20%
When an object is sold at a discount.
You can simply multiply the original price by the discount rate to get the value of the discount.
Original Price * Discount Rate = Value of the discount
Then, you subtract the value of the discount from the Original price to get the discount price
Original Price - Value of the discount = discounted price
Remember: The discount price can also be arrived at by multiplying the Original price with the difference of 100% and the discount rate, in its decimal form.
Original price * (100%-discount rate)/100 = Discount Price
Using the latest formula, we can compute for the original price by dividing the discount price by the difference of 100% and the discount rate, in its decimal form.
Original Price = Discount Price / (100%-discount rate)/100
Original Price = 24 / (100%-20%)/100
= 24 / 0.80
Original Price = 30
Discount Value = 30 * 20%/100%
= 30 * 0.20
Discount Value = 6
Discount Price = 30 - 6
Discount Price = 24
