The Martin’s want to buy a new computer. The regular price is $849. The store is offering a 20% discount and a sales tax of 6% i
kramer

Answer: The total cost of computer would be $719.95

Step-by-step explanation:

I use proportions for these types of problems so we begin with a proportion!

20/100=x/849

100x=16980

x=169.80

Then, after finding how much the discount is, we would subtract it.

849-169.80=679.20

Next, we would find the tax amount with another proportion to find what 6 percent of 679.20 is.

6/100=x/679.20

100x=4075.2

x=40.75

Lastly, we would add the tax, $40.75, plus the total after the discount, $679.20!

Hope this helps! Good luck! (:

Write the equation of a function whose parent function, f(x) = x + 8, is shifted 2 units to the right.
atroni [7]

Answer:

g(x)=x+6

Step-by-step explanation:

we have

f(x)=x+8

If f(x) is shifted 2 units to the right

then

The rule of the translation is

g(x)=f(x-2)

so

g(x)=(x-2)+8

g(x)=x+6
