PLZZZZZZZ help me David is selling floral arrangements. Each arrangement uses 1 vase and 12 roses. Each vase costs David $2.00. Let C be the total cost of the arrangement and r be the cost of 1 rose. Which equation should David use to find the total cost of each arrangement? A. C = 12r + 2 B. C = 2r + 12 C. 12C = r + 12 D. 12 = C + 2r
Cost = 12 roses + $2 for the vase So: C = 12r + 2
