The original cost of a necklace is $32. The jewelry store is having a sale and every item is 30% off. A 6.75% tax rate is charged on the sale price. What is the total cost of the item with the discount and tax included? Use the dropdowns to answer the following question. The sale price of the necklace after the discount is taken is The tax should be calculated using . The tax that should be added is The total cost of the item with the discount and tax included is

Step-by-step explanation:

Original cost = $32

Discount = 30% of 32

Selling price =  32 - 9.60 = $22.40

Tax = 6.75% of 22.40

= $ 1.51

Total cost with discount and tax = 22.40 - 1.51 = $ 20.89

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
