Last summer, Emma's family rented an RV. The rental fee allowed them to use the RV for 8 days. Emma's parents paid an additional $55 for the Great Outdoors upgrade, which included a grill to use for the duration of their trip. Emma's family paid $895 in all. Which equation can you use to find the rental cost, d, of each day they used the RV?
A. 55d + 8 = 895 B. 8d + 55 = 895
C. 895d + 8 = 55 D. 8d + 895 = 55
B. 8d + 55 = 895
