Marge orders the following items and would like to leave a 20 percent tip based on her bill. there is no tax on her meal. what is the total cost of her dinner including gratuity? item amount soup $3.75 shrimp scampi $15.00 iced tea $2.60 dessert $4.25.

The total cost of her dinner including tip would be $30.72

Step-by-step explanation:

Marge orders the following items on her meal.

Soup = $3.75

Shrimp scampi = $15.00

Iced tea = $2.60

Dessert = $4.25

The total cost of her dinner including gratuity is

3.75 + 15.00 + 2.60 + 4.25 = $25.60

She would like to leave a 20% tip based on her bill

Therefore, 20% of $25.60

= 0.20 × 25.60 = $5.12

Now add this tip amount to the bill amount.

$25.60 + $5.12 = $30.72

The total cost of her dinner including tip would be $30.72

560

hope this : )

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
