Chenoa works at a company that is looking into designing hand warmers for hikers. The hand warmers should reach a temperature of 50-55°C and maintain that temperature for 1 hour. She researches safety guidelines and learns that if the hand warmers reach 70°C, they might hurt the user. The company has set a budget of 50 ¢ per hand warmer. CLICK TABLE: ________best meets the constraint of costing 50 cents or less.

• Design 3

• Design 2

• Design 1

Now, Chenoa must determine whether the hand warmers meet the criteria of staying warm for 1 hour. What should she do?

CLICK the TABLE

• Record the temperature of each hand warmer before activating it and 2 minutes after activating it. Determine which hand warmer has the greatest increase in overall temperature.

• • 
    

    Record the temperature of each hand warmer 2 minutes after activating it, then record the temperature again 1 hour later. Compare both temperature readings.

• Record the temperature of each hand warmer immediately after activating it to determine which one reaches its peak temperature most quickly.
