Let x be cost of a tent, y be cost of a bag and z be cost of a camp stool.
The cost of a tent, 3 sleeping bags and 2 camp stools is $175. So equation is,

The price of the tent is 6 times the cost of a camp stool. So equation is,

The cost of sleeping bag is $40 more than the camp stool cost. So equation is,

Substitute the value of x and y in equation x + 3y + 2z = 175 and solve for z.

Substitute the value of z in equation y = 40 + z and equation x = 6z to determine the value of y and z respectively.


So cost of a tent is 30, cost of a sleeping bag is 45 and cost of a camp stool is 5.
