In an office complex of 1000 employees, on any given day some are at work and the rest are absent. It is known that if an employee is at work today, there is an 85% chance that she will be at work tomorrow, and if the employee is absent today, there is a 60% chance that she will be absent tomorrow. Suppose that today there are 760 employees at work. Predict the number that will be at work tomorrow, the following day, and the day after that.

An air conditioner with a power input of 1.2 kW is working as a refrigerator $(\beta=3)$ or as a heat pump $\left(\beta^{\prime}=4\right)$. It maintains an office at 20$^{\circ} \mathrm{C}$ year round that exchanges 0.5 kW per degree temperature difference with the atmosphere. Find the maximum and minimum outside temperatures for which this unit is sufficient.
