Answer 1

a is easy 9.79+3.23+4.22 is what you need to do because he withdrew that from the bank. This equals $17.24.

Answer 2

(a)

he deposited three checks for $34.98, $51.02, and $51.22.

Writing deposited amount as positive: $34.98, $51.02, and $51.22

He withdrew $3.23 for new pencils, $4.22 for cards, and $9.79 for movies

Writing withdrawal amount as negatives: -3.23, -4.22 and -9.79.

(b)

Ordering the rational numbers from least to greatest.

Negatives are smaller than positives.

The greater a negative number, smaller will be its value.

-3.23> -4.22 > -9.79

Now arranging the positive numbers:

34.98< 51.02<51.22

combining them, the correct order from least to greatest is:

-9.79<-3.23< -4.22 <34.98< 51.02<51.22

(c)

At the beginning of the month Jack’s balance was $98.

We add the deposited amount and subtract the withdrawal amount.

98-9.79-3.23-4.22 +34.98+ 51.02+51.22=$217.98

Answer : His balance at the end of the month after all of his deposits and withdrawals is $217.98.
