To determine the temperature at the start of the day, we need to subtract the total increase in temperature from the final temperature of 64 degrees.
The first increase was by 8 degrees, so we subtract 8: 64 - 8 = 56 degrees.
The second increase was by 4 degrees, so we subtract another 4: 56 - 4 = 52 degrees.
Therefore, the expression that shows what the temperature was at the start of the day is 64 - 8 - 4.
The temperature at the end of the day was 64 degrees. The temperature had increased twice during the day, once by 8 degrees and another time by 4 degrees.
Which expression shows what the temperature was at the start of the day?
