Question 3.3. Marco is selling floral arrangements. Each arrangement uses 1 vase and 11 orchids. Each vase costs Marco $4.00. Let C be the total cost of the arrangement and r be the cost of 1 orchid. Which equation should Marco use to find the total cost of each arrangement?

(Points : 1)
11 = C +4r
11C = r + 4
C = 4r + 1
C = 11r + 4
