You bake bread until the internal temperature reaches 365°F. The bread is placed on a table until the internal temperature reaches 88°F and can be sliced. The room temperature is 73°F and the cooling rate of the bread is ( l = 0.075 ). How long do you have to wait until you can slice the bread? Which equation models this situation?

​ (a)   =(​ (b)   )e^​ (c)   +​ (d)  

• 88
• 365-73
• -0.075t
• 73
• 365+73

In 2011, the population of a city was about 238,000. During the next 9 years, the population increased by about 1% each year. Write an exponential model that represents the population y of the city t years after 2011. Then estimate the population in 2020. Round your answer to the nearest thousand.
