Answer :
Final answer:
The temperature of the greenhouse before the heater stopped working must have been at least 68 degrees to ensure that, after a drop of 2 degrees, it was still at least 66 degrees.
Explanation:
To determine the temperature in the greenhouse before the heater stopped working, we know that the temperature dropped by 2 degrees and remained at least 66 degrees afterwards. This means that before the decrease, the temperature had to be at least 2 degrees higher than 66 degrees to still be 66 degrees or higher after the drop.
Thus, the temperature of the greenhouse before the heater stopped working was at least 68 degrees.
