To build a 2100 meter long road, one third of the total length was built on the first day, and one second on the second day. How many meters are left? be deeply grateful
The next day, 1 / 2 * 1 / 3 = 1 / 6 of the total length was repaired
2100 * (1 / 3 + 1 / 6) = 1050m
The remaining 2100-1050 = 1050m has not been repaired
A taxi should pay business tax at 5% of its income and road maintenance fee at 3% of its income. If the monthly income of the taxi is 8000 yuan, it should be paid monthly
Business tax: 8000 × 5% = 400
Road maintenance fee: 400 × 3% = 12
So we have to pay a total of 400 + 12 = 412 yuan
