The solution of the system as an ordered triple (x, y, z) is; (2, 1, 1.25).
The cost of a bouquet of 12 daisies is; $15
Let the cost of roses be x
Let the cost of carnations be y
Let the cost of Daisies be z
Thus, we have the three simultaneous equations as;
12x + 8y + 8z = 42 ------(1)
8x + 6y + 10z = 34.5 ------(2)
10x + 10y + 6z = 37.5 ------(3)
Using online simultaneous equation calculator gives us the values as;
x = 2; y = 1; z = 1.25
Thus, the solution of the system as an ordered triple (x, y, z) is; (2, 1, 1.25).
The cost of a bouquet of 12 daisies is;
Cost = 12 * 1.25 = $15
