Step-by-step explanation:
A)
Withdraws--5.23, -5.22, and -7.89
Deposits-34.98, 51.02, and 51.22
(Rational numbers include integers, whole numbers, decimals that don't repeat or go on forever, and fractions)
B)
-7.89, -5.23, -5.22, 34.98, 51.02, 51.22
(Negatives are less than 0, so when the negative gets bigger, it means that the number is becoming less, so the opposite of positive numbers)
C)
98+34.98+51.02+51.22= 235.22
235.22- 5.22-5.23-7.89= 216.88
216.88 is the answer
(since withdraws are subtracting from the total, you want to add up all of the positive numbers so the deposits plus the amount she had in the beginning, and then subtract the withdraws)
Hope this helps!
