The first step would be to add 7 to both sides.
3n-7=30
add 7
3n=37
divide by 3
n=12.33
Answer:
x < 5
Step-by-step explanation:
2 x +8 < 18

x < 5
We don't know what the question is.
It could be "What is the selling price ?"
If that's the question, then . . .

(1.60 of their cost).
You know their cost. The selling price is (1.60 x $80) .
