Question 16396: Jake paid $100.70 including 6% tax for a color printer. How much did the printer itself cost?
Three consecutive integers are such that the first plus 1/2 the second plus 7 less than twice the third is 2,101. What are the integers?
I am having problems knowing what formulas to use and how to use them. The teacher I have is very vague in her explanations and uses book samples. Thus, I'm having a hard time completing assigned homework. Can you please tell me how to do the above? Thanks a lot, Tom

Let the printer cost be 100% Tax of 6% would make the total cost = 100+6 = 106%
We know that the printer cost $100.70
So 106% = $100.70
How much does 100% = ??
Can you solve it from here?
