The price of the tent is 7 times the cost of a camp stool. The cost of a sleeping bag is $40 more than the cost of a camp stool. Find the cost of each item. \n" ); document.write( "
Algebra.Com's Answer #449861 by sofiyac(983)![]() ![]() You can put this solution on YOUR website! let \n" ); document.write( "camp stools cost x dollars then \n" ); document.write( "tent would cost 7x dollars and \n" ); document.write( "sleeping bag cost would be x+40 \n" ); document.write( "A customer buys a tent, 2 sleeping bags, and 5 camping stools for $220, so now we plug in the above defined cost into this sentence to make equation out of it. \n" ); document.write( "one tent would cost 1*7x \n" ); document.write( "2 sleeping bags would cost 2(x+40) \n" ); document.write( "5 camping stools would cost 5x \n" ); document.write( "Next we add them all up and make the sum equal to 220 \n" ); document.write( "7x+2(x+40)+5x=220 now we solve for x \n" ); document.write( "7x+2x+80+5x=220 \n" ); document.write( "14x=140 divide both sides by 14 \n" ); document.write( "x=10 now go back all the way to the top where we defined how much everything cost and plug in 10 where you see x \n" ); document.write( "camp stools cost x dollars so camp stools cost $10 \n" ); document.write( "tent would cost 7x dollars so tent costs 7*10=$70 \n" ); document.write( "sleeping bag cost would be x+40 so sleeping bag cost is 10+40=$50 \n" ); document.write( " \n" ); document.write( " |
