Question 1201899
.
A store sells tents, sleeping bags, and camp stools. 
A customer buys a tent, 5 sleeping bags, and 2 camp stools for $231. 
The cost of the sleeping bag is $21 more than the cost of a camp stool. 
Find the cost of each item.
~~~~~~~~~~~~~~~~


<pre>
Let x be the price for a camp chair (in dollars).

Then the price for each sleeping bag is (x+21) dollar;
5 sleeping bags cost 5(x+21) dollars.

Let y be the price for the tent.


Then we have one single equation for the total cost

    x + 5(x+21) + y = 231,

or

    6x + 105 + y = 231,

    6x + y = 231 - 105

    6x + y =   126.


Thus we have one equation for two unknowns.


It is not enough to find two unknowns.


The conclusion is that the problem is INCOMPLETE: it does not provide enough information to be solved.
