Bart bought a digital camera with a list price of $219 from an online store offering a 6 percent discount. he needs to pay $7.50 for shipping. what was bart's total cost?

Bart's total cost was $213.36.

Step-by-step explanation:

Hi, to solve this problem you have to calculate the value of the 6 percent discount.

So:

$219 x 0.06 = $13.4

We have calculated the value in money of the discount applied to the list price. The next step is to subtract the discount to the list price.

$219-$13.4=$205.86

Finally, we have to add the shipping cost to obtain the total cost for Bart.

$205.86+ $7.50= $213.36

Bart's total cost was $213.36.

Feel free to ask for more if it´s necessary or if you did not understand something.

is it i think

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
