7,200
Step-by-step explanation:
from 1000-1095 there are 20 multiples of 5
from 1100-1195 there are 20 multiples of 5
from 1200-1295 there are 20
from 1300-1395 there are 20
from 1400-1495 there are 20
from 1500-1595 there are 20
from 1600-1695 there are 20
from 1700-1795 there are 20
from 1800-1895 there are 20
from 1900-1995 there are 20
from 1000-1995 there are 10*20=200 multiples of 5
from 2000-2995 there are 200 multiples of 5
from 3000-3995 there are 200
from 4000-4995 there are 200
from 5000-5995 there are 200
from 6000-6995 there are 200
from 7000-7995 there are 200
from 8000-8995 there are 200
so far there are 8*200=1600 multiples of 5
from 9000-9095 there are 20 multiples of 5
from 9100-9195 there are 20
from 9200-9295 there are 20
from 9300-9395 there are 20
from 9400-9495 there are 20
from 9500-9595 there are 20
from 9600-9695 there are 20
from 9700-9795 there are 20
from 9800-9895 there are 20
from 9900-9999 there are 20
there are another 10*20=200 multiples of 5 to be added to the already 1600 multiples of 5
1600+200=1800 multiples of 5 that are 4-digit numbers
there are 9000 4-digit counting numbers
9000-1800=7200 4-digit numbers that are not multiples of 5
