Answer:
296.97
Step-by-step explanation:
Remark
The first thing you have to realize is that you take the discount before you add the sales tax.
Discount
If she receives a 15% discount, she still pays 85% of the full price.
85/100 * 325 = 276.25
Sales Tax
A sales tax is only added on after a goods or service has been determined and agreed upon by the buyer and seller.
The sales tax can be calculated quickly by adding the decimal equivalent onto 1 and multiplying that by the discounted amount.
1 + 7.5% = 1 + 7.5/100 = 1 + 0.075 = 1.075 deriving the discount amount
Cost
Cost = discounted price * 1.075 Substitute in Formula
Cost = 276.25 * 1.075 Simplify
Cost = 296.97 Answer
The problem given above can be solved through the concept of permutation because of the importance of the arrangements. This may be solved through calculators directly by keying in,
10P5
That is, the permutation of 10 taken 5. The answer to this permutation is 30,240.
the equation is (x - 2)^2 + (y - 7)^2 = 16
Answer:
Step-by-step explanation:
Looking at the diagram,
Line DT is parallel to line line BM, therefore, triangle DHT is similar to triangle BHM. This means that
DH/DB = TH/MH
DH = 15 + 6 = 21
TH = 9 + x
Therefore
(9 + x)/21 = 9/6
Cross multiplying, it becomes
6(9 + x) = 21 × 9 = 189
54 + 6x = 189
Subtracting 54 from the left hand side and the right hand side of the equation, it becomes
6x + 54 - 54 = 189 - 54
6x = 135
Dividing the left hand side and the right hand side of the equation by 6, it becomes
6x/6 = 135/6
x = 22.5
Answer:
Find out the what is the price of oranges this week .
To prove
As given
last week the price of oranges at the farmers market was $1.75 per pound.
This week a price has decreased by 20% .
20% is written in the decimal form
= 0.20
Decreased in the price = 0.20 × 1.75
= $0.35
The price of oranges this week = Price of orange at last week - Decreased in the price
= $1.75 - $0.35
= $ 1.4
Therefore the price of oranges this week is $1.4 .
