At a store , 24 bottles of water and 6 bags of chips costs $23.40. Five bottles of water and two bags of chips cost $6.60. What is the cost of a single bottle of water ?
Answers
24w+6c=$23.40
5w+2c=$6.60
So you have to find c (chips) first. You have to make the number of chips in both equations cancel each other.
-3(5w+2c)=-3($6.60) -15w-6c=$-19.80
Then subtract to get one formula 24w + 6c = $23.40 -15w - 6c = $-19.80
9w = $3.60 w=$.40
To check your answer, find how much one bag of chips costs: 5($.40) + 2c = $6.60 $2.00 + 2c = $6.60 2c = $4.60 c=$2.30
Plug your value for one water and one bag of chips into the formula: 5($.40) + 2($2.30) $2.00 + $4.60 =$6.60
Then plug your values into the original problem: 24($.40) + 6($2.30) $9.60 + $13.80 =$23.40
