Answer:
13 weeks
Step-by-step explanation:
Given that :
Cost of new tub = $312
Planned saving per week = $24

Number of weeks = $312 / $24
Number of weeks = 13 weeks
The temperature of soup after 25 minutes is 
<em><u>Solution:</u></em>
The temperature of chicken soup is 192.7°F
As it cools, the temperature of the soup decreases 2.3°F per minute
Let the initial temperature be 
Let "t" be the time for rate of decrease
Set up an equation
Temperature = Initial temperature - decrease in temperature
Decrease in temperature = rate of decrease x time
Therefore,

<em><u>To find the temperature of soup after 25 minutes, substitute t = 25</u></em>

Thus the temperature of soup after 25 minutes is 
Domain x < or equal to 5
Range y < or equal to -1
