ASAP please give me the answerss!! Due! HELP PLEASE. Part A

Katie just opened a checking account at the bank. Within the first month, she deposited three checks for $21.68, $42.09, and $65.44. She withdrew $4.64 for new pencils, $23.11 for earbuds, and $9.78 for movies from her account in the same month.

Write Katie’s withdrawals as negative rational numbers and her deposits as positive rational numbers.

Part B

Order the rational numbers from least to greatest and explain your reasoning.

Part C

At the beginning of the month Katie’s balance was $128. What was her balance at the end of the month after all of her deposits and withdrawals? You must show your work, no credit will be given for just an answer.

(a) The deposits to be 21.68, 42.09, and 65.44 and the withdrawals to be -4.64, -23.11 and -9.78

(b)

(c)

Step-by-step explanation:

Given

Deposits:  $21.68, $42.09, and $65.44

Withdrawals: $4.64, $23.11 and $9.78

Solving (a): Write out the deposits as positive and the withdrawals as negatives

From (given) above, we have

The deposits to be 21.68, 42.09, and 65.44

and

The withdrawals to be -4.64, -23.11 and -9.78

Solving (b): Order from least to greatest.

Since the withdrawals are negative, the arrangement will start from there because negative numbers are lesser than positives.

Arranging the withdrawals from least to greatest, we have:

-23.11, -9.78, -4.64.

Arranging the deposits from least to greatest, we have:

21.68, 42.09, 65.44

Combine both together;

Solving (c):

Determine the final balance

First we need to get the total deposits:

Next, we determine the total withdrawals:

The final balance is then calculated as:

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

the answer is y = 11.54

hope this : )
