Answer 1

Answer:

Look below

Step-by-step explanation:

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

Deposits: (Q1)

Answer:  -34.98, -51.02, -51.22

Sum of negative rational numbers:

-137.22

Withdrawal's (Q1)

Answer: +5.23, +10.22, + 7.89

Sum of withdrawal's: 23.34

(Q2)-

W: 5.23, 7.89, 10.22

D: -51.22, -51.02, -34.98

Reason: Negative #'s go from lowest to highest (if you are ordering them from highest to lowest) because -34.98 is closer to 0 then -51.02

(Q2) If you are trying to order including each set of #'s it would be:

From least to greatest -51.22, -51.02, -34.98, 5.23, 7.89, 10.22.

(Q3) First, find her sum of the deposits and withdrawals.

Add these: -51.22, -51.02, -34.98, 5.23, 7.89, 10.22.

The answer to that would be $-113.88

Don't forget the tricky negative there. That means that she WOULD be in debt 113.88 dollars. But....

Her balance at the beginning of the month was $128. So from there all you have to do is subtract 128-113.88 which gets you a total offffff: $14.12 .

Lol I worked rly hard on this. Could you do ya boi a favor and give it a big thx ;P or brainliest even?
