You go shopping with a friend and end up buying a shirt for $23.90, a pair of pants for $34.50 and some socks for $3.65. If sales tax is 7.5%, what is your total sales tax amount for all three items?

4.65375

Step-by-step explanation:

Shirt = $23.90

Pants - $34.50

Socks - $3.65

Total Sales = 62.05

7.5% of the total

62.05 x7.5% = 4.65375

The total sales tax amount for all three items is 4.65375

hello i am doing good for you that it's summer in your country or state ; )

btw in my country we just have sun and rain as (because i live in the caribbean lol)

also, thx a lot for the points : )

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1
