Answer:
Milk $3.60
Water $1.80
Chips $0.90.
Step-by-step explanation:
If w = cost of 1 bottle of water, m = cost of 1 gal of milk and c cost of 1 bag of chips we have.
4m + 6w + 5c = 29.7
Also we have w = 2c and m = 1.8 + w.
From the first equation we have c = w/2.
So substituting for c and m in the initial equation we have:
4(1.8 + w) + 6w + 5(w/2) = 29.7
7.2 + 4w + 6w + 2.5w = 29.7
12.5w = 22.5
w = 1. 80.
So c = w/2 = 1.8/2 = 0.90.
and m = 1.8 + 1.8 = 3.60.
The cost of bag of chips is $5.58 , bottle of water is $ 11.16 and gallon of milk is $12.96.
What is an Equation ?
An equation is a mathematical statement formed when two algebraic expressions are equated using an equal sign.
It is given that
4 gallons of milk, 6 bottles of water and 5 snack size bags of chips costs $29.7
Let the price of bag of chips is $x
Then
bottle of water , y costs twice as much as a bag of chips
y = 2x
a gallon of milk , z costs $1.80 more than a bottle of water
z = y +1.8
z = 2x +1.8
The equation that will be formed is
x + 2x + 2x +1.8 = 29.7
5x +1.8 = 29.7
5x = 27.9
x = $5.58
y = $11.16
z = $12.96
Therefore the cost of bag of chips is $5.58 , bottle of water is $ 11.16 and gallon of milk is $12.96.
