In the Founder's Day Parade in Happy, USA, many organizations participate by building floats. The Float Committee has issued a decree that each float can only have 300,000 flowers on it this year. The Happy Campers have already attached 15,625 flowers to their float. If the flowers come in containers which hold 125 flowers, which equation represents how many more containers they can use on their float?

A. 125x + 15,625 = 300,000

B. 125x = 300,000 + 15,625

C. 0x = 300,000 + 125

D. 0x + 125 = 300,000
