Question

The account balance of each of three children at the end of a month is shown below:

Answer 1

Answer:

A)  See attached.

B)  Cheryl owes the bank more.

Step-by-step explanation:

Given account balances:

• John:  -$2.75
• Cheryl:  -$3.00
• Andrew:   $2.75

(Andrew has as much savings in his account as the amount John owes).

Part A

• Draw a straight, horizontal line with arrows on both ends.
• Place a tick in the center of the line and label it zero.
• Draw 4 evenly spaced ticks either side of the zero.
• Number the ticks to the right of the zero 1, 2, 3 and 4.
• Number the ticks to the left of the zero -1, -2, -3, and -4.
• Mark -2.75, -3 and 2.75 on the number line.
• Label the marks with John, Cheryl and Andrew.

(See attached number line).

Part B

The absolute value of a number is its positive numerical value.

To calculate how much John and Cheryl owe the bank, take the absolute values of their account balances:

• John:  |-2.75| = 2.75

• Cheryl:  |-3.00| = 3.00

As 3.00 > 2.75, Cheryl owes the bank more.

Answer 2

Part A (describing the number line):
-Draw a horizontal line
-Put a zero in the middle of the line
-Put -1 to -4 on the left of 0
-Put 1 to 4 on the right of 0
-Draw a dot at -2.75 and label John
-Draw a dot at -3 and label Cheryl

Part B: Cheryl owes the bank more than John. |-2.75| |-3.00| The absolute values are never negative so: 2.75 & 3.00. 3.00 is greater than 2.75.
