Answer (3)
24w+6c=$23.40
5w+2c=$6.60
So you have to find c (chips) first. You have to make the number of chips in both equations cancel each other.
-3(5w+2c)=-3( 6.60 ) − 15 w − 6 c = -19.80
Then subtract to get one formula 24w + 6c = 23.40 − 15 w − 6 c = -19.80
9w = 3.60 w = .40
To check your answer, find how much one bag of chips costs: 5($.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
why does everyone keep doing math question? im horrible at it :( ;
The cost of a single bottle of water is $0.40, calculated from a set of equations based on given total costs for water and chips. We confirmed our answer by finding the cost of chips and verifying both equations. All calculations were consistent with the original problem statements.
