Answer:
2,600
Explanation:
Your first step is to find 7% of 4000 ( this is what it is decreasing by per year).
As a result you end up with 280.
Multiply 280 by 5.
1,400 should be your answer( amount of km decreasing after 5 years). This is a decreasing forest, so you subtract 4,000by 1,400.
Using the standards of conversions, we will find that 1 hg is equivalent to 10000 cg.
Therefore, to convert 420 hg to cg, all you have to do is cross multiplication as follows:
420 hg = (420 x 10000) / 1 = 4200000 cg
The correct choice is: 4200000
If 62% of the seats are sold;
100-62= 38% seats still available.
17100=38% seats available
17100/38= seats in 1%
450 seats
In 100%,
450×100=450000 seats total.
