Final answer:

The temperature in San Antonio, TX increased by 1.25 degrees per hour until 7:00 PM and then dropped by 19 degrees at midnight. The temperature at midnight was 62°F. Therefore, the correct option is d).

Step-by-step explanation:

The temperature in San Antonio, TX starts at 66°F at 7:00 AM and increases by 1.25°F per hour until 7:00 PM.

From 7:00 PM to midnight, the temperature remains constant. At midnight, the temperature drops by 19°F.

To find the temperature at midnight, we need to calculate the total temperature increase from 7:00 AM to 7:00 PM and then subtract the temperature drop of 19°F.

Temperature increase from 7:00 AM to 7:00 PM

= 12 hours x 1.25°F/hour

= 15°F

Temperature at midnight = Temperature at 7:00 PM + Temperature increase from 7:00 AM to 7:00 PM - Temperature drop at midnight

= 66°F + 15°F - 19°F

= 62°F

The temperature at midnight was 62°F. Therefore, the correct option is d).
