The next month, Tim’s dad gave him permission to withdraw $35 to buy a new video game. Tim’s dad explained that the bank would charge a $5 fee for each withdrawal from the savings account and that each withdrawal and charge results in a debit to the account.
In the third column, write down any new words and definitions that you learn during the discussion.

Example 2:
How Hot, How Cold?
Temperature is commonly measured using one of two scales, Celsius or Fahrenheit. In the United States, the Fahrenheit system continues to be the accepted standard for nonscientific use. All other countries have adopted Celsius as the primary scale in use. The thermometer shows how both scales are related.
a. The boiling point of water is 100°C. Where is loo degrees Celsius located on the thermometer to the right?
Answer:
It is not shown because the greatest temperature shown in Celsius is 50°C.
b. On a vertical number line, describe the position of the integer that represents 100°C.
Answer:
The integer is 100, and it would be located 100 units above zero on the Celsius side of the scale.
c. Write each temperature as an integer.
i. The temperature shown on the thermometer in degrees Fahrenheit:
Answer:
100
ii. The temperature shown on the thermometer in degrees Celsius:
Answer:
38
iii. The freezing point of water in degrees Celsius:
Answer:
0
d. If someone tells you your body temperature is 98. 6°, what scale is being used? How do you know?
Answer:
Since water boils at 100°C, they must be using the Fahrenheit scale.
e. Does the temperature 0 degrees mean the same thing on both scales?
Answer:
No. 0°C corresponds to 32°F, and 0°F corresponds to approximately – 18°C.
