Alice Smith bought a clothes dryer that retailed for $325 . She received a 15% discount because she works at the store where she
r-ruslan [8.4K]

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

aliya0001 [1]
 <span>Vertex (3, 2): 

h = 3 
k = 2 


Point (4, 6): 

x = 4 
y = 6 


Vertex Form: 

y = a(x - h)² + k 


Subbing known values, 

6 = a(4 - 3)² + 2 
6 = a(1)² + 2 
6 = a + 2 
a = 6 - 2 
a = 4 


Equation: 

y = 4(x - 3)² + 2</span>
