Kate bought a book for $14.95, a record for $5.85, and a tape for $9.70. if the sales tax on these items 6 percent and all 3 items are taxable, what is the total amount she must pay for the 3 items including tax?

The total amount that she must pay for the 3 items including tax is $32.33

Step-by-step explanation:

Kate bought a book for $14.95, a record for $5.85, and a tape for $9.70. Total cost of the three items would be

14.95 + 5.85 + 9.7 = $30.5

If the sales tax on these items is 6 percent and all 3 items are taxable, it means that the amount of tax paid on the 3 items would be

6/100 × 30.5 = $1.83

The total amount that she must pay for the 3 items including tax would be

30.5 + 1.83 = $32.33

understand that i don't know the answers

will someone answer his question

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
