The cost of a bottle of orange juice is equal to the cost of two
bottles of milk. 3 bottles of orange juice and 5 bottles of milk
equals 66 dollar
How much is the cost of a bottle of milk
Let the cost of Orange Juice be "x".
Cost of Bottle of Milk be "y".
Since the cost of a bottle of orange juice is equal to the cost of two bottles of milk.
cost of a bottle of orange juice = cost of two bottles of milk
x = 2*y (1)
3 bottles of orange juice and 5 bottles of milk equals 66 dollar
3x + 5y = 66 // one bottle of Orange Juice = x then 3 bottles cost is "3x"
Put x = 2y
3(2y)+ 5 y = 66
3(2y) + 5y = 66
6y + 5y = 66
11 y =66
y = 6
Therefore the cost of bottle of milk is 6 dollar
