Let the cost of a camp stool be $x$. Then, the cost of a sleeping bag is $x + 30$, and the cost of a tent is $7x$. The total cost is given by $7x + 3(x + 30) + 3x = 220$. Simplifying, we get $13x + 90 = 220$, leading to $13x = 130$, so $x = 10$. Thus, a camp stool costs $10, a sleeping bag costs $40 ($10 + 30$), and a tent costs $70 ($7 \times 10$).
