Its saying that every 2 years the students decreases by 30 such as in 1990 the number of students in an large urban high school is 3490.In 1992 the number of students was 3460 and keep decreasing every 2 years 30 comes off.
The easiest way to move faster is to:
Years=The Number Of Students
2006=2200
2008=2170
2010=2140
2012=2110
2014=2080
2016=2050
But here is the tricky part the question said 2017 it an odd number so we have half of 30 because 30 comes of every 2 years but its the 1st year so it half of the 2 years and half of 30 students so this equals to:
2017=2035
1 cm is regular
but 1 cm 2
means that you multiply 1 by 1 which is 1
for example if you have 15cm 2 you would multiply 15 by 15 and get 225
and 15 cm 3 would be 15*15*15 and you would get 3375
