The account balance of each of three children at the end of a month is shown below:
xeze [42]

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).

<h3><u>Part A</u></h3>
  • 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).

<h3><u>Part B</u></h3>

The <u>absolute value</u> of a number is its <u>positive numerical value</u>.

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.
