问题 解答题

李先生打算购买一套住房,如果分期付款,有两种付款方式:一种是开始第一年先付17.5万元,以后每年付款2.5万元;另一种付款方式是提前一半时间每年付款4万元,后一半时间每年付款3万元.这两种付款方式的总额和付款年限都相同,那么,李先生购买这套住房共需付款多少元?

答案

设付款年限为x年,根据题意得:

17.5+(x-1)×2.5=x÷2×4+x÷2×3,

17.5+2.5x-2.5=2x+

3
2
x,

15+2.5x=3.5x,

15+2.5x-2.5x=3.5x-2.5x,

x=15;

17.5+(15-1)×2.5,

=17.5+14×2.5,

=17.5+35,

=52.5(万元);

答:李先生购买这套住房共需付款52.5万元.
