Algebra one word problem, help please?
Don't give me the direct answer because I don't want to be cheating, just tell me how I am supposed to set this up as an equation;
Do-Nothing #1 can count 5 more ceiling dots per minute than Do-Nothing #2. If they work together for 30 minutes straight, they can count a (combined) total of 3,450 dots. How many dots can Do-Nothing #2 count per minute?
(Again, I'm only asking HOW to set this up to solve, and tell me why you got the equation that you do as your answer, thanks!)

Let rate of count for #2 be x per min
so rate of counting dots for #1 is x+5 per min
They work straight for 30 mins
so #2 counts 30x dots
and #1 counts 30(x+5) dots
total dots counted is 3450
so 30x+ 30(x+5) = 3450
You can solve further
Hope this helps
