Answer:
300x+120y
Step-by-step explanation:
Given that Charlotte places 15 tulips and 6 violets in a bouquet.
Thus cost of one bouquet will include cost of tulips and violets
Cost of tulip in one bouquet = 15*x = 15x
Cost of viiolet = 6*y =6y
Total cost for one bouquet = [tex]15x+6y[/tex]
1 Bouquet costs = [tex]15x+6y[/tex]
So 20bouquets would cost
= [tex]20(15x+6y)\\= 300x+120y[/tex]
