Answer:

40.95

Step-by-step explanation:

If the jacket is 40% off, you still have to pay 100% -40% or 60%

The new price is the original price times 60%

new price = 65*60%

                 =39

We need to find the sales tax

tax= price * tax rate

    = 39 * 5%

   = 39 *.05

   =1.95

Final cost is the new price plus the tax

Final cost = 39+1.95

                 =40.95

40% off means you are paying 60% of the original price ( 100% - 40% = 60%


Multiply the price of the coat by 60%:

65.00 x 0.60 = 39.00 ( sale price)

Now multiply the sale price by 1.05 ( price of coat plus tax rate) to get the final cost:

39.00 x 1.05 = 40.95


The final price is $40.95

The correct answer is: Option 3: (hofog)(x)=\frac{x-14}{x+4}

Step-by-step explanation:

Given

f(x)=\frac{x-6}{x}\\g(x)=x+4\\h(x)=3x-2

We have to find

(hofog)(x)

This will be equal to:

h(f(g(x)))

So we have to find the composition of (fog)(x) first

(fog)(x) = f(g(x))\\=\frac{x+4-6}{x+4}\\=\frac{x-2}{x+4}

Now,

(hofog)(x)=h(f(g(x)))\\=3(\frac{x-2}{x+4})-2\\=\frac{3x-6}{x+4}-2\\=\frac{3x-6-2(x+4)}{x+4}\\=\frac{3x-6-2x-8}{x+4}\\=\frac{x-14}{x+4}

The correct answer is: Option 3: (hofog)(x)=\frac{x-14}{x+4}
