I'm awful at word problems someone

to host school groups on field trips, a museum charges a flat fee of $250 plus $8 for each student who attends. if a school can spend at most $585 for it's field trip to this museum, what is the maximum number of students the school can afford to send?

a)40
b)41
c)42

Your answer is B.

Flat fee is $250, so we cannot change this number.
585 - 250 = 335
335 (remaining cash) divided by 8 (price per student) = 41.875
Since we can't bring .8 of one student on the trip, we will round the number down to 41, because if we round up we will go over the budget of $585.

The maximum number of students a school can send is 41.

The clear answer is clearly 25 is very clear to me
