If the base price of a concert ticket is 30$ and a handling subcharge of 15% is added to the price, what is the total cost of ticket?

34.50$

Step-by-step explanation:

To calculate the value of the surcharge we need to multiply the base price of the ticket (30$) by the rate of the surcharge (15% or 0.15).

30 * 0.15 = 4.50

Then we add this surcharge (4.50$) to the base price of the ticket (30$) to get the total value of (34.50$).

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

a) 0

i^413 x i^0 = 0 as any number multiplied by a zero is
