1一阶非齐次线性差分方程组及其解的结构1．1一阶线性差分方程组某出租车公司在A、B两城各设有一营业部,A、B两城营业部每天分别有10％,12％的出租车被租用开到对方城市并留在对方城市供租甩设an、bn分别表示第n天A、B两城可供出租的汽车数,试建立两城每天可供出租汽车数的模型．出租车公司关心的是每个营业部每天都至少要保持分别有120辆车供出租,如果一开始时A、B两城分别有120、150辆车供租用,能保持吗?
1The structure of first-order non-homogeneous linear difference equations and their solutions1.1 First-order linear difference equations A taxi company has a sales office in each of the A and B cities. The sales offices of A and B cities have 10%, 12% of taxis are rented to the other city and stay in the other city for rent. An, bn means the number of cars available for lease in city A and B on the nth day respectively. Try to build two cities for daily use. Model of several taxis. Taxi companies are concerned that each sales department must maintain at least 120 vehicles for rent every day. If there are 120 and 150 vehicles in the A and B cities for rent at the beginning, can they be maintained?
