Answer:
y = 2.50x + 3
Step-by-step explanation:
In this case 2.50 is the variable (which means that x goes with it) because to find the total cost of the flowers you would have to multiply 2.50 by the total number of flowers ordered.
Since there is only 1 vase and this price does not vary it is the constant.
Therefore the equation can be written like this:
y = 2.50x + 3
