Formulate but do not solve the problem. The total number of passengers riding a certain city bus during the morning shift is 900. If the child's fare is $0.25, the adult fare is $0.75, and the total revenue from the fares in the morning shift is $475, how many children and how many adults rode the bus during the morning shift? Let x be the number of children.

Let the number of adults be y. Then we know that:

- x + y = 900 (total number of passengers)
- 0.25x + 0.75y = 475 (total revenue from fares)

We have two equations and two variables, so we can solve for x and y. However, we are only asked to formulate the problem, not solve it. Therefore, the correct answer is B, which presents the two equations without solving for x and y.
