Question

The temperature on a summer day was 88°F. During the night, the temperature fell 17°F. Which expression represents one way to calculate the temperature in the morning?

1) 17 - 88
2) 88 - (-17)
3) -88 + 17
4) 88 - 17

Answer 1

The correct expression to calculate the morning temperature after a decrease of 17°F from 88°F is 88 - 17.

Step-by-step explanation:

The expression that represents one way to calculate the temperature in the morning after it fell 17°F during the night from 88°F is 88 - 17. When the temperature decreases, we subtract the decrease from the initial temperature. Thus, the correct expression to find the morning temperature is to subtract 17°F from 88°F.
