Final answer:
The correct expression to calculate the morning temperature after a fall of 17°F from 88°F is (d) 88 - 17, which results in 71°F.
Step-by-step explanation:
The question is about how to calculate the temperature in the morning after it falls 17°F from 88°F during the night. The correct mathematical expression to represent this calculation is 88 - 17. In this context, option (d) 88 - 17 is the one that correctly represents the calculation, as it simply subtracts the drop in temperature from the initial temperature. Therefore, the temperature in the morning would be 71°F.
