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
Answer:
The rate of change is 1
Step-by-step explanation:
In order to calculate the rate of change, take two points (in this example I'll use points (8, 2) and (10, 4)) and input them into this expression used to calculate rate of change: 
Solve:
4 - 2 = 2
10 - 8 = 2
2/2 = 1
The rate of change is 1.

Answer:
Remember the interior and exterior angle add up to 180°.
Answer:Let x and (x-3) represent Elvira's and David's times respectively
D = r*t
Distances traveled are equal in this example***
14mph*x = 21mph(x-3)
solving for x
14x = 21x - 63
63 = 7x
x = 9hr, the time that Elvira traveled. David traveled 6hrs (9hr-3hr = 6hr)
CHECKING our Answer***
14mph*9hr = 126mi = 21mph*6hr = 126mi
