Page 102 Question 8

[1] What is 96% of 80,000 yuan?

"2" is the result of the question 1. What is the percentage of 1.5%?

Page 103 Question 9

1 interest tax = principal * interest rate * time *5%

The fifth question 105 page

Ditto.

p 102 t8:( 1)80000 x96 %(2)76800 x 1.5%

=80000x0.96 =76800x0.0 15

=76800 (yuan) = 1 152 (yuan)

p 103 T9:( 1)300 X5 %(2)300 x5.4 % x3

=300x0.05 =300x0.054x3

= 15 (yuan) =48.6 (yuan) 300+48.6=348.6 (yuan)
