Riley just opened a checking account at the bank. within the first month, she deposited three checks for $34.98, $51.02, and $51.22. she withdrew $5.23 for new pencils, $10.22 for earbuds, and $7.89 for movies from her account in the same month. write riley’s withdrawals as negative rational numbers and her deposits as positive rational numbers. order the rational numbers from least to greatest and explain your reasoning. at the beginning of the month riley’s balance was $128. what was her balance at the end of the month after all of her deposits and withdrawals? show your work, no credit will be given

Part 1:

Rational numbers have both demoninator and numerator as integers

Riley's withdrawals:

5.23 ----  -

10.22 --- -

7.89 ---- -

Riley's Deposits:

34.98 ----

51.02 ----

51.22 ----

Part 2:

Order the rational numbers:

a - -----Least

b -

c -

d-

e-

f- ---- Greatest

Reasoning: Above the rational numbers are ordered from least to the greatest and they are represented by alphabets from a to f

Lets take the first rational number a =   and compare it with the 5 other rational numbers. If it is less than all 5 numbers than that means it is the smallest one, this process will be applied on all rational numbers until all are sorted out.

Part 3:

Balance at the beginning: $128

Total Deposits: 34.98 + 51.02 + 51.22 = $137.22

Total Withdrawals: 5.23 + 10.22 + 7.89 = $23.34

Balance at the end of month: Total Deposits - Total withdrawals

= 137.22 - 23.34

Balance at the end of month = $113.88

40 x 50 = 2000
