To solve this you would divide until you can’t. I recommend staying in whole numbers:) I always divide by twos because I think it’s more efficient! 4 divided by 2 is 2 and 30 divided by 2 is 15 sooo (2 hours to 15) hope this helped!
6,00 because you have to add them up then divide the the last nimber and you should get 6,000
F(x)=2(3)-5
f(x)=6-5
f(x)=1
X=5.2
Hope this was helpful
