1. 1. Total price of two washing machines: 35 1÷ 13%=2700 yuan.

2. Type B washing machine has more 500 yuan than Type A, so the price of Type B is 2700÷2+500÷2= 1600 yuan.

The price of model A is1600-500 =1100 yuan.

Actual payment made by Xiao Wang1600 (1-13%) =1392 yuan.

What Xiao Wang actually paid was1100 (1-13%) = 957 yuan.

2.- 10-8 ÷(-2)×(- 1/4)

=- 10+4×(- 1/4)

=- 10- 1

=- 1 1

(-24) × ( 1/4- 1/3+5/8)+(-2)?

=(-24)×(6/24-8/24+ 15/24)+4

=(-24)× 13/24+4

= - 13+4

= - 9
